The solution of the equation sin^(3)x+sin x cos x+cos^(3)x=1 is (n in N)2n pi(b)(4n+1)(pi)/(2)(2n+1)pi(d) None of these

Let n be a natural number such that n gt 4 and U_(n) =sin ^(n) x+ cos ^(n)x. Then which of the following is correct ?

Find the derivative of y=sin^(m)x.cos^(n)x.

The least value of n for which (n -2) x^(2) + 8 x + n + 4 gt sin^(-1) ( sin 12) + cos^-1)( cos 12),AA x in R", where " n in N , is ..............

If sin^(4)x+cos^(4)y+2=4sin x cos y then the value of sin x+cos y is equal to

Prove that (i) cos (n + 2) x cos (n+1) x +sin (n+2) x sin (n+1) x = cos x) (ii) " cos " .((pi)/(4)-x) " cos " .((pi)/(4)-y) " - sin " ((pi)/(4)-x ) " sin " ((pi)/(4) -y) =" sin " (x+y)

sin (n +1) x sin (n +2) x + cos (n +1) x cos (n +2) x = cos x

sin (n +1) x sin (n +2) x + cos (n +1) x cos (n +2) x = cos x

sin (n +1) x sin (n +2) x + cos (n +1) x cos (n +2) x = cos x

sin (n +1) x sin (n +2) x + cos (n +1) x cos (n +2) x = cos x
