Evaluate: 4/cot square 30 degree+1 / sin 60 degree- cos square 45
Added by Mark V.
Step 1
First, we need to simplify the expression inside the parentheses: cot^2(30°) = (cos(30°)/sin(30°))^2 = (sqrt(3)/1)^2 = 3 sin(60°) = sqrt(3)/2 cos^2(45°) = (cos(45°))^2 = (sqrt(2)/2)^2 = 1/2 Now we can substitute these values into the expression: 4/cot^2(30°) + Show more…
