Answer to Problem 133AYU
Explanation of Solution
Given information:
Write a brief paragraph that explain how to quickly compute the trigonometric functions of
Calculation:
Consider a right triangle as shown.
By using angle sum property of triangle, equal angle have equal side opposite to them,
So,
Now apply Pythagorean Theorem we get,
Now,
Now reciprocate the identities,
Now consider equilateral triangle as shown,
Apply Pythagorean Theorem to
Now by using reciprocal and quotient identity,
Now by using reciprocal and quotient identity,
Hence,
