" (v) "sin3x+cos2x=0

Find the general solution for each of the following equations : (i) cos4x=cos2x (ii) cos3x=sin2x (iii) sin3x+cos2x=0 (iv) sinmx+sinnx=0

Solve the trigonometric equation : sin 3x + cos 2x = 0

cosx - sin3x = cos2x

Solve the trigonometric equation: sin3x+cos2x=0

Solve sin 3x = cos 2x. (0 lt x lt 2pi).

lim_(x rarr0)(sin3x cos2x)/(sin2x)

cos3x-sin2x=0

Number of solution(s) of the equation (sin x)/(cos3x)+(sin3x)/(cos3x)+(sin2x)/(cos27x)=0 in the interval (0,(pi)/(4)) is

sin^(2) x+2sin x cos x-3cos^(2) x = 0 if (i) tan x = 3 (ii) tan x = -1 (iii) x = n pi+(pi)/(4) , n in I (iv) x = n pi+tan^(-1) (3), n in I
