Question

find general solution of cos x=-√3/2​

Answer 1

Answer:

solution of cos x=-√3/2​

Step-by-step explanation:

As  

cos

x =√ 3 2 ,  

x  is positive and hence can be in  

either first quadrant i.e.  

x = π 6

or in fourth quadrant i.e.  

x = − π 6  

Further adding  ± 2 π  to  x

too does not change value of  

cos x  

Hence  

x= 2 π ± π 6 , where  

n  is an integer.
