solvefor x,2cos(x)+sqrt(3)=0

solve for

x, 2 cos (x) + 3 = 0

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

Solution steps

2 cos (x) + 3 = 0

Move

3

to the right side

2 cos (x) = - 3

Divide both sides by

2

cos (x) = - \frac{3}{2}

General solutions for

cos (x) = - \frac{3}{2}

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

4 cos (x) - 5 = - 8

sin (x) + 4 csc (x) + 5 = 0, 0 \leq x \leq 2 π

r = a sin (3 x)

sin (x) = \frac{18}{25}

3 cos (x) - sin^{2} (x) + 3 = 0
