You would have to use its opposite tangent, tan-1on your scientific calculator. It would be tan-1(opposite side/adjacent side), and you must have the opposite and adjacent sides of the angle you are trying to solve.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
WARNING: Do not, under any conditions, look at the sun, directly or indirectly.The find the elevation of the sun, measure the angle that an object's shadow from the sun makes. One way to do this is with a stick in the ground. Assuming the stick is perpendicular to the ground, the ratio of the stick's length to the shadow's length is the tangent of the angle of elevation. Solve for inverse tangent, and you have the angle.
To find the angle of elevation of the sun, we can use the tangent function. The tangent of an angle is equal to the opposite side (height of the tree) divided by the adjacent side (length of the shadow). So, tan(angle) = height of the tree / length of the shadow. Plugging in the values, we get tan(angle) = 40 / 58. Taking the arctan of both sides gives us the angle, so the angle of elevation of the sun is approximately 33.56 degrees.
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
Well, isn't that a happy little question! The inverse tangent of 0.3125 is approximately 17.5 degrees. Just imagine that angle gently resting in a meadow of mathematical serenity, bringing balance and harmony to your calculations. Remember, there are no mistakes in math, just happy little numbers waiting to be discovered.
Take the inverse tangent -- tan-1(opposite side/adjacent side)
Using trigonometry: tangent = opposite/adjacent
To find the coefficient of static friction on an incline, you can use the formula: coefficient of static friction tan(angle of incline). Measure the angle of the incline using a protractor, then calculate the tangent of that angle to find the coefficient of static friction.
The degree of an angle can be determined using the tangent function. From one ray of the angle, draw a perpendicular line until it intersects the other ray of the angle. Measure the length of the first ray (A) and the perpendicular line (B) and set as a ratio of B/A. This ratio is equal to the tangent of the angle.
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A

Given only the measure of an angle, use a scientific calculator or a book of mathematical tables (if you can find one!). There are infinite series but they are not particularly easy to work with.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
