Find the derivative of f(x) = x²sinx

• f'(x) = 2xsinx - x²cosx
• f'(x) = 2xsinx + x²sinx
• f'(x) = 2xsinx + x²cosx
• f'(x) = 2xcosx

Find the derivative.

 $P\left(x\right)=\left(x^6-5\right)\left(x^4+5\right)$  

•  $P'\left(x\right)=10x^9+20x^5-30x^3$  

•  $P'\left(x\right)=10x^9+30x^5+20x^3$  

•  $P'\left(x\right)=10x^9+30x^5-20x^3$  

•  $P'\left(x\right)=10x^9-30x^5-20x^3$  

Calculate the derivative, if f(x) = -25xcos(x)

• f'(x)= -25xsin(x) + 25cos(x)

• f'(x)= -25xsin(x) - 25cos(x)

• f'(x)= 25xsin(x) - 25cos(x)

Calculate the derivative if f(x) = 2x³ sin(x)

• f'(x)= -2x³ sin(x) + 6x²cos(x)

• f'(x)= 2x³sin(x) + 6x²cos(x)

• f'(x)= -2x³cos(x) + 6x²sin(x)

• f'(x)= 2x³cos(x) + 6x²sin(x)

Calculate the derivative if f(x) = x² cos(x) + 10x²

• f'(x)=x²cos(x)+2xsin(x) + 20x

• f'(x)=-x²sin(x)+2xcos(x) + 20x

• f'(x)=x²sin(x)+2xsin(x) + 20x
