cos(θ)= 3/(sqrt(11))

Solution

cos (θ) = \frac{3}{11}

Solution

θ = 0.44051 \dots + 2 πn, θ = 2 π - 0.44051 \dots + 2 πn

+1

Solution steps

cos (θ) = \frac{3}{11}

Simplify

\frac{3}{11} : \frac{3 11}{11}

Apply trig inverse properties

θ = arccos (\frac{3 11}{11}) + 2 πn, θ = 2 π - arccos (\frac{3 11}{11}) + 2 πn

Show solutions in decimal form

θ = 0.44051 \dots + 2 πn, θ = 2 π - 0.44051 \dots + 2 πn

Popular Examples

(30)/(sin(90))=(30)/(sin(x)),x

\frac{30}{sin ( 9 0 ^{\circ} )} = \frac{30}{sin ( x )}, x

(sec(x))/(cos(x))-1=0

\frac{sec ( x )}{cos ( x )} - 1 = 0

-9(sin(x))^2+2sin(x)+2=0

- 9 (sin (x))^{2} + 2 sin (x) + 2 = 0

cos^2(x)-2cos(x)+1=0,0360

cos^{2} (x) - 2 cos (x) + 1 = 0, 0^{\circ} 36 0^{\circ}

sin^4(x)=sin^2(x),0<= x<2pi

sin^{4} (x) = sin^{2} (x), 0 \leq x < 2 π
