Plugging in the point (y1,y2,y3)=(1,−2,4) yields the answer∂p∂y3(1,−2,4)=9(1−2)1(−2)(1−2+4)2=2. What is the first partial derivative? F (x,y,z) = 4x3y2 −ezy4 + z3 x2 +4y −x16 f ( x, y, z) = 4 x 3 y 2 − e z y 4 + z 3 x 2 + 4 y − x 16 solution. For the partial derivative with respect to r we hold h constant, and r changes: The first time you do this, it might be easiest toset y=b, where b is a constant, to remind you that you shouldtreat y as though it were number rather than a variable.

Once you understand the concept of a partial derivative as the rate that something is changing, calculating partial derivatives usually isn't difficult. G(x, y, z) = xsin(y) z2. Thederivative is just the derivative of the last term with respect tox3, which is∂f∂x3(x1,x2,x3,x4)=5x1x4substituting in the values (x1,x2,x3,x4)=(a,b,c,d), we obtainthe final answer∂f∂x3(a,b,c,d)=5ad.

The ugly term does not depend on x3, so in calculatingpartial derivative with respect to x3, we treat it as a constant.the derivative of a constant is zero, so that term drops out.

F (r, h) = π r 2 h.

For the partial derivative with respect to r we hold h constant, and r changes: (the derivative of r2 with respect to r is 2r, and π and h are constants) it says as only the radius changes (by the tiniest amount), the volume changes by 2 π rh. Partial derivatives tell you how a multivariable function changes as you tweak just one of the variables in its input.about khan academy: F y ( x, y) = ( x 2 − 15 y 2) cos ( 4 x) e x 2 y − 5 y 3 f y ( x, y) = ( x 2 − 15 y 2) cos ( 4 x) e x 2 y − 5 y 3.
