Simplify sin(pi/6)^2+cos(pi/6)^2
Problem
Solution
Identify the trigonometric identity applicable to the expression. The Pythagorean identity states that for any angle
θ the sum of the squares of sine and cosine is equal to1
Substitute the specific angle
θ=π/6 into the identity.
Verify by evaluating the individual trigonometric functions. We know that
sin(π/6)=1/2 andcos(π/6)=√(,3)/2
Simplify the squared values and sum them.
