Just substitute these values: \[\sin ^{2}60=(\frac{\sqrt{3}}{2})^{2}\] \[\tan ^{2}30=(\frac{1}{\sqrt{3}})^{2}\] \[\sin 45=\cos 45=\frac{ \sqrt{2}}{2}\]

What part didn't you get? You just need to plug in the values that I gave and simplify.

3 + 1  4 = ? Do you want to know how the exact values for the trig ratios are derived?

@Rohangrr , kropot72 basically gave you the answer, his work is spot on. If you follow each of this work from each post, you'll get to the right answer, which, as he/she said in their last response, is 0
