cos(x)=0.3,cos(pi-x)

cos (x) = 0.3, cos (π - x)

No Solution for x \in R

Solution steps

cos (x) = 0.3, cos (π - x)

Apply trig inverse properties

cos (x) = 0.3

General solutions for

cos (x) = 0.3

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

x = arccos (0.3) + 2 πn, x = 2 π - arccos (0.3) + 2 πn

x = arccos (0.3) + 2 πn, x = 2 π - arccos (0.3) + 2 πn

Solutions for the range

cos (π - x)

No Solution for x \in R
