cos(a)=0.24

cos (a) = 0.24

a = 1.32843 \dots + 2 πn, a = 2 π - 1.32843 \dots + 2 πn

Degrees

a = 76.11345 \dots^{\circ} + 36 0^{\circ} n, a = 283.88654 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (a) = 0.24

Apply trig inverse properties

cos (a) = 0.24

General solutions for

cos (a) = 0.24

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

a = arccos (0.24) + 2 πn, a = 2 π - arccos (0.24) + 2 πn

a = arccos (0.24) + 2 πn, a = 2 π - arccos (0.24) + 2 πn

Show solutions in decimal form

a = 1.32843 \dots + 2 πn, a = 2 π - 1.32843 \dots + 2 πn

sin (x) = 1 5^{\circ}

cos (a) = 0.42

\frac{6}{sin ( 6 0 ^{\circ} )} = \frac{4}{sin ( x )}

10 = 14 + 8 sin (\frac{π t}{12})

sin (4 x) cos (x) - cos (4 x) sin (x) = 1
