cos(b)= 5/13

cos (b) = \frac{5}{13}

b = 1.17600 \dots + 2 πn, b = 2 π - 1.17600 \dots + 2 πn

Solution steps

cos (b) = \frac{5}{13}

Apply trig inverse properties

b = arccos (\frac{5}{13}) + 2 πn, b = 2 π - arccos (\frac{5}{13}) + 2 πn

Show solutions in decimal form

b = 1.17600 \dots + 2 πn, b = 2 π - 1.17600 \dots + 2 πn

x, sin (x) = \frac{1}{3}

tan (A) = \frac{5}{12}

cos (\frac{x}{2}) = \frac{1 - cos ( x )}{2}

0.322 = sin (3.92232 \cdot x)

x, arcsin (y) = arcsin (x)
