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 ...
As background, learn tovisualize the trig functions, and how they're related by the Pythagorean Theorem and similarity: Part 1: Learn the table First, let's learn to make the table, one column at a time: Function:The function to derive (sin, cos, tan, cot, sec, csc) Sign:The "pri...
. The hypotenuse, therefore, must have length 4 by the Pythagorean theorem. Now, we're going to start by defining the sine of q (written "sin q") as the length of the opposite side, divided by the length of the hypotenuse; so we'll say that sin 30o = (2 divided by 4) = 1/...

You can simplify any trig function of any inverse trig function in two easy steps, using this method: Think of the inner arcfunction as an angle. Draw a right triangle and label that angle and the two relevant sides. Use the Pythagorean Theorem to find the third side of the triangle, ...
≤θ≤π. Using the Pythagorean 3 Theorem and the fact that θ is in the second quadrant we get that sin(θ) = √ 5 2 −3 2 5 = √ 25−9 5 = 4 5 . Note that although θ does not lie in the restricted domain we used to define the arcsin function, the unrestricted sin...
In week one, we learned a simple yet extremely useful math concept, the Distance Formula. This formula uses the Pythagorean Theorem to determine the distance between two points on the rectangular coordinate system. Variations of the Pythagorean Theorem such as the Distance Formula can be used in ...
Applying the Pythagorean Theorem to the unit circle, the Pythagorean Identity arises: $$\sin^2+\cos^2=1\hspace{1cm}(2) $$ This particular identity can be manipulated in a variety of ways to produce other identities. Next are the addition and subtraction identities, $$\sin(\alpha+\beta)...
