1)if a and b are complemaentary angles find values of sin sq(pi/2-a)+sin sq(pi/2-b)

sq-square
2)if ABCD is a cyclic quadrilateral find tan sq (A+C/2)-cos sq (B+D/2)

What is the definition of complimentary angles?

Show us your work!

I assume you mean "sq" means the squares of the various trig functions:

1) \(\displaystyle \displaystyle \sin^2(\pi/2-a) + \sin^2(\pi/2-b)\)

How are sines of complementarity angles related?

2) What does "cyclic quadrilateral" mean? Are ABCD the sides, or the vertices? Can you draw a picture?
