Chapter  3 Trigonometric Functions Exercise   3.4

 Question 1:

Find the principal and general solutions of the equation 

Therefore, the principal solutions are x =and.

Therefore, the general solution is


Find the principal and general solutions of the equation 

sec x=2

cos x=1/secx=1/2

x=Π/3

cos(2Π-x)=cosx

cos(2Π-Π/3)=cos(5Π/3)=1/2

principal solutions are Π/3 and 5Π/3

cosx=cosΠ/3

x=2nΠ±Π/3 ,n∈Z, is the general solution


Find the principal and general solutions of the equation 

tanx=-1/√3

tan Π/6=1/√3

tan(Π-x)=-tanx=-1/√3

tan(Π-Π/6)=tan(5Π/6)=-1/√3

tan(2Π-x)=-tanx=-1/√3

tan(2Π-Π/6)=tan(11Π/6)=-1/√3

principal solutions are 5Π/6 and 11Π/6

tanx=tan5Π/6

x=nΠ+5Π/6, n∈Z is the general solution


Find the general solution of cosec x = –2

cosec x = –2

Therefore, the principal solutions are x =.

Therefore, the general solution is


Find the general solution of the equation 


Find the general solution of the equation 


Find the general solution of the equation 

Therefore, the general solution is.


Find the general solution of the equation 

Therefore, the general solution is.


Find the general solution of the equation 

Therefore, the general solution is
