Each of the four statement given below are either True or False. I. `sin 765=-1/sqrt2` II. `cosec(-1410)=2` III. `tan(13pi)/3=1/sqrt3` IV. `cot(-(15pi)/4)=-1`

Each of the four statements given below are either True or False.sin765^(@)=-(1)/(sqrt(2))

True or False statements : sec^-1(1/sqrt3) + cosec^-1 (1/sqrt3) = pi/2

True or False statements : sin^-1 sqrt3 + cos^-1 sqrt3 = pi/2

Write whether the following statements are true or false. "tan"^(-1)4/(3)+"cot"^(-1)((-3)/(4))=pi

Which of the following statement is(are) true or false: (i) tan^(-1)(1)=(pi)/(4) (ii) "sin"^(-1)(pi)/(2)= not defined (iii) tan^(-1)x="cot"^(-1)(1)/(x) (iv) "cosec"^(-1)x="sin"^(-1)(1)/(x), |x| ge 1
