cos(θ)= 3/5 ,0<θ< pi/2

cos (θ) = \frac{3}{5}, 0 < θ < \frac{π}{2}

θ = 0.92729 \dots

Solution steps

cos (θ) = \frac{3}{5}, 0 < θ < \frac{π}{2}

Apply trig inverse properties

θ = arccos (\frac{3}{5}) + 2 πn, θ = 2 π - arccos (\frac{3}{5}) + 2 πn

Solutions for the range

0 < θ < \frac{π}{2}

θ = arccos (\frac{3}{5})

Show solutions in decimal form

θ = 0.92729 \dots

sin (x) - cos^{2} (x) sin (x) = - 1

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

(cot (θ) + 1) (csc (θ) - \frac{1}{2}) = 0

tan^{2} (x) = 1 + sec^{2} (x)

cos (x) = \frac{50}{86}
