Create a table of trig values


x 0 30 45 60 90

sin 0 1/2 √2/2 √3/2 1


cos 1 √3/2 √2/2 1/2 0


tan 0 √3/3 1 √3 dne


Use this table to find the exact answer!

yes, I know but I want to see the steps to evaluating the expression and dividing the numerator, etc. Not just plugging in the numbers and getting the answer.

((sqt(2)/2)*(sqt(3)))/((1/2)*(sqt(3)/2) simplify the algebra to get 2*sqt(2)

By the way, did you see my updated answer to the sin^2a-cos^2a-tan^2a problem
