sin^(-1)(sin ((7pi)/6))

" (a) "int_(0)^( pi/6)sqrt(1-sin2x)dx" का मान ज्ञात कीजिए "

sin^(-1)(sin((7pi)/6)) is

sin pi/3 = 2sin pi/6 cos pi/6

The value of sin ""(pi)/(16) sin ""(3pi)/(16) sin ""(5pi)/(16) sin ""(7pi)/(16) is

The value of sin ""(pi)/(16) sin ""(3pi)/(16) sin ""(5pi)/(16) sin ""(7pi)/(16) is

sin(pi/18)*sin(5pi/18)*sin(7pi/18)

What is the value of [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] ? [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] का मान क्या है?

"sin"^(4)(pi)/(16) + "sin"^(4) (3pi)/(16) + "sin"^(4) (5pi)/(16) + "sin"^(4) (7pi)/(16)=
