हु COS UV — =24. यंदि 8 न 30 तो सिद्ध �

1.	हु COS UV — =24. यंदि 8 न 30 तो सिद्ध करें कि(i) _(l/ =g 8) (1 + ००४ है) - Ml(1—sin B) (1 + sin B) 32... D
Answer» B = 30 ((1-cosB)(1+cosB))/((1-sinB)(1+sinB)) = ((1-√3/2)(1+√3/2))/((1-1/2)(1+1/2)) = ((2-√3)(2+√3))/((2-1)(2+1)) = (4-3)/(1*3) = 1/3 If you find this answer helpful then like it.

Answer»

B = 30 ((1-cosB)(1+cosB))/((1-sinB)(1+sinB)) = ((1-√3/2)(1+√3/2))/((1-1/2)(1+1/2)) = ((2-√3)(2+√3))/((2-1)(2+1)) = (4-3)/(1*3) = 1/3
