Trigonometry

You can calculate that on any scientific calculator. Just make sure that the calculator is set to "degrees". As a check, the sine of 90° should come out as exactly 1.

Whether tanning indoors or outdoors, it is important to be safe. You should NEVER overexpose yourself. It is the OVEREXPOSURE that can cause skin damage, not the exposure itself. If you are going to tan indoors, be sure to tan no more than every other day. Going every day can increase your chances of overexposure thus increasing your chances of skin damage. Don't spend more than the time recommended for you skin type in a tanning bed or too much time outside in the sun. The biggest problem among people these days is that if they pay for a 15 minute tanning bed, they expect to get 15 minutes even though they end up burning themselves. Tanning properly is a gradual process. Not an instant one.

A response to:

"you can go to a tanning bed but that can give you skin cancer"

For the record, tanning beds will not necessarily give you cancer. At least not any more than the sun. Most people who get skin cancer were most likely predisposed to get it anyway. (i.e., family history of cancer/skin cancer) Actually, most skin conditions that are diagnosed as "cancer" are really not. Only a very small percent are malignant. The rest are benign. Only the malignant ones can be considered cancer. The benefits that you get from tanning or sun exposure (such as increased Vitamin D production) are far greater than the risks.

If I give you a 600mL of medicine for 2 adults and 1 child. The child takes 37% of the adult dosage. What are the doses? .....yes, you need algebra.

If I got a beaker that is 12 mm high and the mouth opening is 2mm wide, and I ask you to give me a 41.4 cubic mm of a solution, ......yes, you will need trigonometry.

Yes

cos2 x + sin2 x = 1

cos2 x = 1 - sin2 x

Its periodicity and amplitude remain the same.

Yes.

Non-linear partial differential equations. Are you offering to help me? If not, why did you ask?

You can solve for sin18 by making use of trigonometry.

plane trigonometry

spherical trigonometry

False.

The smallest angle will be opposite the smallest side of the triangle and so by using the cosine rule it works out as 43.84 degrees.

It also equals 13 12.

I suggest that it is (sin A)^2 + (cos A)^2 = 1

Tangent is used in calculus to compute the slope of a curve. Because curves do not have uniform slopes, unlike lines, their slopes change. A tangent is the slope of a curve at a specific point.

The corresponding angles in both cases are the same. With congruent triangles, the lengths of the corresponding sides are also equal.

180/10 = 18 square meters of cross-sectional area.

Since the prism is a triangle, that means that the height x width = 36, since A = (H*W)/2

Therefore you could say 6x6, 18x2, 4x9, or even 36x1.

Just remember SOHCAHTOA,

SOH is using the sine, only use this when you have the Hypotenuse and the Opposite.

Sin(a)= O/H

CAH is using the cosine, only use this when you have the Hypotenuse and Adjasent.

Cos(a)=A/H

TOA is using the tangent, only use this when you have the Opposite and Adjasent.

Tan(a)=O/A

At the bottom, the car has kinetic energy of ½mv2. At the top, the car has kinetic energy of 0. If we ignore friction and wind resistance, the initial kinetic energy is converted to gravitational potential energy of mgh, where the m is again the mass of the car, g is the acceleration of gravity, and h is the vertical change in position of the car. Solving the two equations for h, we get

h=½v2/g=(0.5)(25 m/s)2/(9.8 m/s2)=31.888 m

To find the distance traveled along the road, we use a bit of trigonometry: sin(30°) = h/d = 0.5, so d = 2h = 63.776 meters

Of course, the actual value will be less, due to the friction and wind resistance that we ignored in our calculations.

The answer depends on the context. The applications will vary from one context to another.

There are agricultural fields.

There are vector fields in physics which depict the magnitudes and directions of forces.

There are algebraic structures called fields which have some mathematical properties associated with them.

You find the angle with a fixed direction using trigonometry. You then convert it to an angle measured in degrees, clockwise from North, and written as a three digit number.

If y=xm2+76l-k+sl3474?

The specific location of something or in which something is occurring or has happened, or the measurement of something that happened or is happening is a point in geometry.
