2.x^(20)

Find the second order derivatives of the function. x^(20)

If x is the root of the equation x^(2) -ix -1 =0 , then The value of x^(20) + 1/x^(20) may be

If x is the root of the equation x^(2) -ix -1 =0 , then The value of x^(20) + 1/x^(20) may be

x^(18) + x^(12)=0, x^(20) + x^(14)= 0

(d^(20))/(dx^(20))(2cos x cos3x)=2^(20)(cos2x-2^(20)cos4x)(b)2^(20)(cos2x+2^(20)cos4x)(c)2^(20)(sin2x+2^(20)sin4x)(d)2^(20)(sin2x-2^(20)sin4x)

(d^(20)y)/(dx^(20))(2cosxcos3x)is equal to 2^(20)(cos2x-2^(20)os3x) 2^(20)(cos2x+2^(20)cos4x) 2^(20)(sin2x+2^(20)sin4x) 2^(20)(sin2x-2^(20)sin4x)

(d^(20))/(dx^(20))(2cosxcos3x)= 2^(20)(cos2x-2^(20)cos4x) (b) 2^(20)(cos2x+2^(20)cos4x) (c) 2^(20)(sin2x+2^(20)sin4x) (d) 2^(20)(sin2x-2^(20)sin4x)

Evaluate : int sqrt(14x-20-2x^(2))dx
