Question

please give me some trigonometry question for cbse class10

Answer 1

..................

. Hope it helps

Answer 2

1)  If x sin3|+ y cos3|=sin|cos| and xsin|=ycos|, prove x2+y2=1.

  2) Find the value of (sin°45- cos°45)

3)   If tan|+sin|=m and tan|- sin|=n, show that (m2-n2)=4√mn

4) If cosec |-sin |=l and sec |- cos |=m, prove that l2m2(l2+m2+3)=1

5)  If sin A=1/2, then find the value ofcos A.

6)   If cosec |=3x and cot |=3/x. then find the value of (x2-1/x2)

7) Given cosec|=4/3, calculate all other trigonometric ratios.

I hope it will help you....
