सिद्ध कीजिये कि
`1 + 8 sin^(3) 10^(@) = 6 sin 10^(@)`

3sin10^(@)-4sin^(3)10^(@)=

(1-4 sin 10^(@) sin70^(@))/(2 sin 10^(@))=

Find the value of : (8 sin ^3 10^@-6sin10^@)

sin^(10)x-cot^(8)x=1

The value of sin^(-1) (sin 10) is

The value of sin^(-1) (sin 10) is

I : sin^(2) 42^(@) - sin^(2) 12^(@)=(sqrt(5)+1)/(8) II : 8 cos^(3) 10^(@) - 6 cos10^(@)= sqrt(3)

The equation of an FM signal is e = 6 sin (10^(6) t + 4 sin 10^(3) t ) . Then, the modulating frequency is
