cos(x)=0.8736

cos (x) = 0.8736

x = 0.50824 \dots + 2 πn, x = 2 π - 0.50824 \dots + 2 πn

Solution steps

cos (x) = 0.8736

Apply trig inverse properties

x = arccos (0.8736) + 2 πn, x = 2 π - arccos (0.8736) + 2 πn

Show solutions in decimal form

x = 0.50824 \dots + 2 πn, x = 2 π - 0.50824 \dots + 2 πn

4 cos (A) + 3 = 2 cos (A) + 4

sin^{2} (x) - tan (x) = 0

6 sin^{3} (x) + 7 sin^{2} (x) - sin (x) - 2 = 0

2 sin (x) cos^{2} (x) - sin (x) = 0

tan (x) = \frac{1}{sec ( x )}
