To calculate the value of the sine of an obtuse angle–an angle between 90 and 180 degrees–subtract it from 180 to derive the equivalent acute angle. Step 3 Calculate the sine value for one angle by dividing opposite side by adjacent side. Step 4 Find the quotient of sin(a)/A, and ...

The Pythagorean Theorem can be used to find a side length when two sides of a right triangle are known. Sine, cosine, and tangent can be used to solve for missing sides if at least one side and one acute angle in a right triangle are known. The function used is determined by the ...
In trigonometry, the period of a function refers to the distance of a function's wave. Learn how to find the period of a trig function by exploring...
For example, to find the derivative of sine, we need: and we let $dx$ go to zero. This is tricky to work on directly, but using the $\sin(a + b)$ formula we have As $dx$ goes to zero, $\cos(dx) = 1$ (zero angle is full width), so we have: ...
You find trigonometric values and ratios with the30°and60°triangles in the exact same manner as with the45°triangle (ya know:SOH CAH TOA). Affiliate What if I'm not allowed to draw pictures to find the angle values? If your instructor doesn't want you drawing pictures to help you re...
To find the normal vector of any given vector, divide both components of the vector by the vector's length. Multiplication. Multiplying a vector by a scalar factor will increase the magnitude of the vector. An easy way to do this is to multiply both components by the scalar f...
For example, if you have an angle A = 40°, you can find sin A≈ 0.64. But you have to go the other direction when you’re solving a triangle. For instance, you might get sin B = 0.82 and have to find the angle B. You’re not asking what’s the sine of some angle, but ...
