The most common Pythagorean identities are: sin²x + cos²x = 1 1 + tan²x = sec²x.Unit Circle Trig Identities. The six basic trigonometric functions can be verified using the unit circle. Remember that for a right triangle with acute angle {eq}\theta {/eq}:To arrive at this answer, we apply the Pythagorean theorem: Recall the formula a² + b² = c², where a, and b are the legs and c is the hypotenuse. In our case, a = b, so the formula reads 2a² = c². Solving for a, we get a = c/√2. Plugging in c = 10, we get the final answer: a = 10/√2 ≈ 7.07. Piotr Małek and Mateusz Mucha.
