Trigonometry

It comes from the name of the town 'balaclava' in crimea. The face coverings were knitted in Britain then sent over to British troops.

The derivative of (sin (theta))^.5 is (cos(theta))/(2sin(theta))

In analytical geometry, you equate the equations of the two planes and simplify.

a2 = b2 + c2 - 2bc cos(alpha)

b2 = a2 + c2 - 2ac cos(beta)

c2 = a2 + b2 - 2ab cos(gamma)

There are all three formulas. Do not forget to use, arc-cos, when finding angles.

Yes.

What best way to teach mathematics

sec(x)=1/cos(x) - (hint: look at the third letter: sec->(1/)cos,

cosec->(1/)sin, cot->(1/)tan)

pi divided by 6 is a constant and so its first derivative is 0. And since that is also a constant, the second derivative is 0. It is not clear what f(x) = csc(x) has to do with that!

If you are in school and are studying trig then you are using trig in real life.

asdasdas

It is a polynomial of the fourth degree in X.

A lot of people think that the face in geometry is the side of a three dimensional figure, but it can really mean the specific side of a 2-d figure as well. Face just means the front of a figure for the side you're looking at. You can have the face of a circle, for example. It just means the side of the circle you're referring to.

It is 82 degrees and 12 minutes, as in the question = 82.2 deg = 1.4347 radians.

• there is a variable component of motion in the direction at right angles to the direction of propagation of the wave.
• acceleration is directly proportional to displacement from the direction of propagation of the wave, and
• the direction of acceleration is opposite to that of the displacement.

It is a trigonometric function whose argument is the number theta.

There are 59875200 ways.

According to Math experts, Hipparchus, Menelaus, and Ptolemy are responsible for developing Greek trigonometry for the purposes of studying differences in shapes of the planets, sun and moon. By observing the shapes of each, they were able to determine the ratios and areas of each one.

Trigonometry mainly but also geometry, algebra.

The tangent (of a curve) is a vector that is tangent (perpendicular to the normal), i.e. the instantaneous velocity of the curve at a specific point. As such, the initial tangent is the initial velocity of the curve at the point where t=0.

Stated in other terms, the tangent is the slope of the line at a point. This is expressed (in two dimensions, but applicable to higher dimensions), as the line that has x and y coordinates equal to the point of tangency, and slope equal to the limit of delta y over delta x as delta x (and delta y) approaches zero.

Yes a tangent is a straight line thattouches a curve at only one point

But there is a tangent ratio used in trigonometry

Change all the signs.

Suppose you have the quadratic equation: y = ax2 + bx + c

Its additive inverse is -ax2 - bx - c.
