Review articles. This phrase here means the cosine, of theta, equals adjacent over hypotenuse.

And the last one here is for the tangent. It says the tangent of theta, equals opposite over adjacent. Opposite divided by adjacent. Opposite over adjacent. So, soh cah toa helps you remember your trig functions. So lets take that idea over here, and draw a line out, and make some calculations. We have a graph here of a unit circle.

That means the radius of this is one everywhere. And what I want to know is, here's my angle theta. And angles are measured from the positive X axis. Here's the X axis. Here's the Y axis.

Angles are measured in two ways. Angles are measured in degrees.

From zero to And angles are also measured in something called radians. And that goes from zero to two pi. So these are two different angle measures. And when you're measuring in degrees, we put the little degree mark up here. That's what that means. Radians don't get a degree mark on them.

So if I mark this out in degrees, here's zero degrees. Here's 90 degrees. Here's degrees. This is And when I get back to the beginning, it's degrees. If I measure the same angles in radians, this'll be zero radians. When I get back here it's gonna be two pi radians. Going all the way around the circle is two pi radians. Using these values in conjunction with reference angles and signs of the functions in the different quadrants, you can determine the exact values of the multiples of these angles.

Cheat Sheet. Trigonometry For Dummies Cheat Sheet. Formulas to Help You in Trigonometry Many of the formulas used in trigonometry are also found in algebra and analytic geometry. Special Right Triangles Every right triangle has the property that the sum of the squares of the two legs is equal to the square of the hypotenuse the longest side.

When you have a right triangle, the measure of the hypotenuse is always twice the measure of the shortest side, and the other leg is always or about 1. Right Triangle Definitions for Trigonometry Functions The basic trig functions can be defined with ratios created by dividing the lengths of the sides of a right triangle in a specific order. Coordinate Definitions for Trigonometry Functions The trig functions can be defined using the measures of the sides of a right triangle.

Signs of Trigonometry Functions in Quadrants An angle is in standard position when its vertex is at the origin, its initial side is on the positive x -axis, and the terminal side rotates counterclockwise from the initial side. Laws of Sines and Cosines The laws of sines and cosines give you relationships between the lengths of the sides and the trig functions of the angles. Exact Trigonometry Functions for Selected Acute Angles Using the lengths of the sides of the two special right triangles — the right triangle and the right triangle — the following exact values for trig functions are found.

Express Sine in Terms of Cotangent Even though each trigonometry function is perfectly wonderful, being able to express each How to Create a Table of Trigonometry Functions The angles used most often in trig have trig functions with convenient exact values. Commonly Used Values of Selected Trig Functions When performing transformations in trig functions, such as rotations, you need to use the Using the Method of Undetermined Coefficients If you need to find particular solutions to nonhomogeneous differential equations, then yo
