Sorry, but if you're stupid enough to go dabble in unprotected sex without the intention of making kids, I sincerely hope you got pregnant. And aids to go with it.
Traffic lights have been in widespread use since the 1920s. Roundabouts, in their modern form, were developed in the 1960s. There were circular road junctions since the early years of the 20th century, but the rules and conventions governing their use were markedly different from modern roundabouts.
It varies where you live, but most places can be a high of 100*+- in the early summer, and a high of 60 +- in winter times.
Nadir, being the lowest point in a series of measured levels, is accepted in both noun and verb forms. To speak of tumor markers after treatment for certain cancers, they will "nadir" at some point before they begin to rise, indicating biochemical recurrence, or one may anticipate levels "nadiring" early in the presence of more aggressive disease.
Trigonometry was probably developed for use in sailing as a navigation method used with astronomy.[2] The origins of trigonometry can be traced to the civilizations of ancient Egypt, Mesopotamia and the Indus Valley (India), more than 4000 years ago.[citation needed] The common practice of measuring angles in degrees, minutes and seconds comes from the Babylonian's base sixty system of numeration. The first recorded use of trigonometry came from the Hellenistic mathematician Hipparchus[1] circa 150 BC, who compiled a trigonometric table using the sine for solving triangles. Ptolemy further developed trigonometric calculations circa 100 AD. The ancient Sinhalese in Sri Lanka, when constructing reservoirs in the Anuradhapura kingdom, used trigonometry to calculate the gradient of the water flow. Archeological research also provides evidence of trigonometry used in other unique hydrological structures dating back to 4 BC.[citation needed] The Indian mathematician Aryabhata in 499, gave tables of half chords which are now known as sine tables, along with cosine tables. He used zya for sine, kotizya for cosine, and otkram zya for inverse sine, and also introduced the versine. Another Indian mathematician, Brahmagupta in 628, used an interpolation formula to compute values of sines, up to the second order of the Newton-Stirling interpolation formula. In the 10th century, the Persian mathematician and astronomer Abul Wáfa introduced the tangent function and improved methods of calculating trigonometry tables. He established the angle addition identities, e.g. sin (a + b), and discovered the sine formula for spherical geometry: : Also in the late 10th and early 11th centuries, the Egyptian astronomer Ibn Yunus performed many careful trigonometric calculations and demonstrated the formula : Persian mathematician Omar Khayyám (1048-1131) combined trigonometry and approximation theory to provide methods of solving algebraic equations by geometrical means. Khayyam solved the cubic equation x3 + 200x = 20x2 + 2000 and found a positive root of this cubic by considering the intersection of a rectangular hyperbola and a circle. An approximate numerical solution was then found by interpolation in trigonometric tables. Detailed methods for constructing a table of sines for any angle were given by the Indian mathematician Bhaskara in 1150, along with some sine and cosine formulae. Bhaskara also developed spherical trigonometry. The 13th century Persian mathematician Nasir al-Din Tusi, along with Bhaskara, was probably the first to treat trigonometry as a distinct mathematical discipline. Nasir al-Din Tusi in his Treatise on the Quadrilateral was the first to list the six distinct cases of a right angled triangle in spherical trigonometry. In the 14th century, Persian mathematician al-Kashi and Timurid mathematician Ulugh Beg (grandson of Timur) produced tables of trigonometric functions as part of their studies of astronomy. The mathematician Bartholemaeus Pitiscus published an influential work on trigonometry in 1595 which may have coined the word "trigonometry" itself. Hope that helps. :)
He made his observations with very simple instruments, using an ordinary plumb-line to measure the angles of elevation of the stars. He also introduced a mathematical innovation by using Hindu-Arabic numerals in his sine tables, the first transition from the duodecimal to the decimal system.
As long as you have your period, no matter when it comes, you cannot be pregnant. Pregnancy delays periods until months after the baby is born, typically. You cannot, however, be pregnant and have your period.
if your period comes on early does that mean that you are not pregnant?
It is doubtful However if you often have unprotected sex you should be worried because it only a matter of time before she is pregnant.
Yes, my mother had her periods while pregnant with me. Your ovulated egg can stay in your body several days before dissolving if not fertilized with sperm.
If you did not go back on the pill immediately after your period ended, then yes you could be pregnant.
no...i wouldn't think so...cuz u've had ur period
No.
it always varies whaen you have your period. When you are pregnant you do not get a period.
Maybe.
No.
birth control pills do things with your hormones, if you are not following the instructions properly you throw out the hormonal balance and end up with things like early or late period or pregnancy. it sounds like your period has started early because of the way you did it, so it is unlikely that you are pregnant.
when you have your period, that means youre not pregnant. when you have your period, that means youre not pregnant. when you have your period, that means youre not pregnant. when you have your period, that means youre not pregnant.
