There are three Pythagorean Identities, and you can get from one to the other with a little algebra magic. One of these identities is: sin^2(θ) + cos^2(θ) = 1. But how do we know that adding “sine of theta squared” plus “cosine of theta squared” truly equals one? (Fyi, sin^2(θ) is the same thing as…
A radian is an angle with its vertex at the center of a circle. In trigonometry, this maybe used as an alternative to measuring angles in degrees. To do this, you multiply the angle in degrees by pi and divide by 180.
This is part 2 of 2 on Solving Trigonometric Equations (see Solving Trigonometric Equations Part 1 for problems 1 to 5). In this tutorial I will solve several different trigonometric equations using different techniques such as factoring, substitution and converting the equation to all one trigonometric function using identities. Solving trigonometric equations involves knowledge of…

This problem uses trigonometric identities to solve. It was found in the Princeton Review’s Math Level 2 SAT Subject Test book.
x(2y-5)=y+4 in this question our goal is to factor everything to one side and figure out what y equals out to.
Trigonometry has baffled students for many because because of the difficulty in learning the basic values but alas it’s quite easy and I’ll show you how.
The understanding of the Unit Circle is foundational in trigonometry. For a detailed background introduction to the concept of the Unit Circle, click here.
Pythagorean theorem introduces the key equation to solving lengths of a right triangle’s side. (A right triangle being one that has a 90 degree angle). With the givens of two side lengths (denoted as a, b, and c, in the respective order of lengths) the equation a^2 + b^2 = c^2 can be used.
