-J-PI8.If sin a + cosec a = 2, n€z, find the value of sin power "n" a+cosec power "n" a​

Answer»

HEY MATE HERE'S THE SOLUTION..... ❤️❤️❤️❤️

GIVEN :

\sin(a)  +  \csc(a)  = 2

TO FIND :\sin {}^{n} (a)  +  \csc {}^{n} (a)  =  \gamma

Find gamma?

SOLUTION :

RAISE BOTH SIDES OF GIVEN EQUATION TO "n"

==>( \sin  (a)  +  \csc {} (a) ) {}^{n}  = 2 {}^{n}

Now using BIONOMIAL theorem you can solve further...

REMEMBER : \sin( \alpha )  \times  \csc( \alpha )  = 1
