` y= 3cos x ` का ग्राफ `0^(@) ` से `360^(@) ` तक खींचिए|

sin x + cos (x + 30 ^ (@)) = 0,0 ^ (@)

Solve cos x - sqrt3 sin x =1, 0^(@) le x le 360 ^(@).

sin 5x - sin3x - sinx=0 (0^(@) lt x lt 360^(@))

sin x + cos (x + 30^(@)) = 0, 0 ^(@) lt x lt 360^(@)

cos2theta - cos 4theta = 0 (0^(@) lt theta lt 360^(@))

Solve the equations for which solution lies in the interval 0^(@) lt theta lt 360^(@) . 2 cos^(2)x + 1 = - 3 cos x

y = tan ^ (- 1) ((1) / (cos ^ (2) x + cos x + 1)) + tan ^ (- 1) ((1) / (cos ^ (2) x + 3cos x + 3)) upto n terms then y '(0) =

Solve the equations for which solution lies in the interval 0^(@) lt theta lt 360^(@) . cos 2x = 1 - 3 sin x

Solve: sin 5x - sin 3x - sin x =0, 0^(@) lt x lt 360^(@).

For what value of x between 0^(@) and 360^(@) does cos 2x=2cos x?
