cos(B)= 3/8

cos (B) = \frac{3}{8}

B = 1.18639 \dots + 2 πn, B = 2 π - 1.18639 \dots + 2 πn

Degrees

B = 67.97568 \dots^{\circ} + 36 0^{\circ} n, B = 292.02431 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (B) = \frac{3}{8}

Apply trig inverse properties

cos (B) = \frac{3}{8}

General solutions for

cos (B) = \frac{3}{8}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

B = arccos (\frac{3}{8}) + 2 πn, B = 2 π - arccos (\frac{3}{8}) + 2 πn

B = arccos (\frac{3}{8}) + 2 πn, B = 2 π - arccos (\frac{3}{8}) + 2 πn

Show solutions in decimal form

B = 1.18639 \dots + 2 πn, B = 2 π - 1.18639 \dots + 2 πn

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

2 sin^{2} (\frac{1}{2} x) + C = - 2 cos (\frac{x}{2}) sin (\frac{x}{2}) + C

4 sec^{2} (x) = 8

cos (x) = \frac{3. 6 ^{2} + 5. 3 ^{2} + c ^{2}}{2 ( 3.6 \cdot 5.3 )}

3 \cdot sin (x) - cos (x) = 2
