Show that cos^2 (60°) + sin^2 (60°) = 1 using this right angled triangle.

opposite opposite is 30°.sin^2(t) + cos^2(t) = 1 for any angle-you can draw diagram and simply put the value of cosine and sine....it gives u the relation u asked about.......

triangle: hypotenuse = 2
opposite = 1
adj. = sqrt of 3.
angle between hyp and adj, opposite opposite is 30°.

Let the legs be x and y and the hypotenuse r
Then x^2+y^2 = r^2
x^2/r^2 + y^2/r^2 = 1
sin^2(t) + cos^2(t) = 1 for any angle
