47=cos(x),x

4 7^{\circ} = cos (x), x

No Solution for x \in R

Solution steps

4 7^{\circ} = cos (x), x

Switch sides

cos (x) = 4 7^{\circ}

Apply trig inverse properties

x = arccos (4 7^{\circ}) + 36 0^{\circ} n, x = 36 0^{\circ} - arccos (4 7^{\circ}) + 36 0^{\circ} n

Solutions for the range

x

No Solution for x \in R

cos (α) = \frac{7}{11}

x, m^{2} - m - 2 = sin (x)

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

- 15 sin (3 x) = 0

sin (θ) = - \frac{5}{3} cos (2 θ)
