solvefor x,pi+3arccos(x+1)=0

solve for

x, π + 3 arccos (x + 1) = 0

No Solution for x \in R

Solution steps

π + 3 arccos (x + 1) = 0

Move

π

to the right side

3 arccos (x + 1) = - π

Divide both sides by

3

arccos (x + 1) = - \frac{π}{3}

0 \leq arccos (x) \leq π

No Solution for x \in R

cos (x + 4 0^{\circ}) = 0.3

cos (3 x) = - 1, 0 \leq x \leq 2 π

sin (x) = - 3 cos (x)

4 sin^{2} (x) + 2 cos^{2} (x) = 3, 0 \leq x \leq 2 π

sin (x) = - 5
