A student is finding the derivative of f(x)=1+0.2x−cos(πx) Their steps are numbered 1-3 below. Is there an error in one of the steps? 1. dxdf(x)=dxd1+dxd0.2x−dxdcos(πx) 2. =0+0.2−−sin(πx) 3. =0.2+sin(πx) Yes, there is an error in step 3. Yes, there is an error in step 1. Yes, there is an error in step 2. No, there is no error.
