sin(θ)= 7/25 ,cos(θ/2),0<θ<90

sin (θ) = \frac{7}{25}, cos (\frac{θ}{2}), 0^{\circ} < θ < 9 0^{\circ}

No Solution for θ \in R

Solution steps

sin (θ) = \frac{7}{25}, cos (\frac{θ}{2}), 0^{\circ} < θ < 9 0^{\circ}

Apply trig inverse properties

sin (θ) = \frac{7}{25}

General solutions for

sin (θ) = \frac{7}{25}

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

θ = arcsin (\frac{7}{25}) + 2 πn, θ = π - arcsin (\frac{7}{25}) + 2 πn

θ = arcsin (\frac{7}{25}) + 2 πn, θ = π - arcsin (\frac{7}{25}) + 2 πn

Solutions for the range

cos (\frac{θ}{2})

No Solution for θ \in R

sin (2 x) = - \frac{1}{4}

2 cos^{4} (θ) - 3 cos^{2} (θ) + 1 = 0

2 cos^{2} (θ) + 7 cos (θ) - 4 = 0

sec^{4} (x) = sec^{2} (x) tan^{2} (x) - 2 tan^{4} (x)

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