Solution: 15sin2θ + 2cos2θ = 7 or, 15sin2θ + 2[ 1 - sin2θ ] = 7 or, 15sin2θ + 2 - 2sin2θ = 7 or, 13sin2θ   = 7 - 2 or,  sin2θ = 5 / 13  taking .....

Here,  B+C  = π ==>  B = π - C SinB= sin(π-c)           = sinc  So, LHS =  2( 1 - sinbsinc)= 2(1 - sin2(c))  = 2cos2(c)  = [2cos2(c) - 1] + 1  = cos(2c) .....

First of all, we need to prove that if x + y + z = 0 then = 3xyz x + y + z = 0 x + y = - z = = = Add 3xyz -3xyz (that is 0) to the right hand side = Factor -3xy from the first three terms on the right hand side = -3xy(x .....

Here,       2tan3x.cos2x + 1 = tan3x + 2cos2x or, 2tan3x.cos2x - 2cos2x - tan3x + 1 = 0 or, 2cos2x(tan3x - 1) - (tan3x - 1) = 0 or, (tan3x - 1)(2cos2x - 1) = 0 ==> Either, tan3x - 1 = 0 ==> tan3x = 1    .....

Here, 2cos3A + 2sin2A cosA = 5sinA cos2A  or, 2cosA [ cos2A + sin2A] = 5sinA cos2A  or,  2cosA  = 5sinA cos2A               [ Since,   cos2A + sin2A = .....
