solvefor x,cos(x)= 1/4

solve for

x, cos (x) = \frac{1}{4}

x = 1.31811 \dots + 2 πn, x = 2 π - 1.31811 \dots + 2 πn

Solution steps

cos (x) = \frac{1}{4}

Apply trig inverse properties

x = arccos (\frac{1}{4}) + 2 πn, x = 2 π - arccos (\frac{1}{4}) + 2 πn

Show solutions in decimal form

x = 1.31811 \dots + 2 πn, x = 2 π - 1.31811 \dots + 2 πn

cos^{2} (t) = 0

sin (x) = \frac{18}{12}

csc (θ) = 5

cot^{2} (x) = tan (\frac{x}{2})

cos (x) = \frac{15}{21}
