We have
w=evu+v2 

Then,
wu=(0)(u+v2)ev(1)(u+v2)2 
wu=ev(u+v2)2 
wv=(ev)(u+v2)(ev)(2v)(u+v2)2 
wv=(u+v22v)ev(u+v2)2 
wu=ev(u+v2)2 
wv=(u+v22v)ev(u+v2)2

First, let's find wu:
Using the quotient rule, we have:
wu=u(ev)·(u+v2)(ev)·u(u+v2)(u+v2)2
Now, let's calculate each partial derivative:
u(ev)=0
since v does not contain u.
Next,
u(u+v2)=1
as u is being differentiated with respect to u, and v2 does not contain u.
Substituting these results back into the expression for wu, we get:
wu=ev(u+v2)2
Now, let's find wv:
Again using the quotient rule, we have:
wv=v(ev)·(u+v2)(ev)·v(u+v2)(u+v2)2
Now, let's calculate each partial derivative:
v(ev)=ev
since v is being differentiated with respect to v, and u does not contain v.
Next,
v(u+v2)=2v
as v2 is being differentiated with respect to v, and u does not contain v.
Substituting these results back into the expression for wv, we get:
wv=ev·(u+v2)(ev)·2v(u+v2)2
Therefore, the first partial derivatives of the function w are:
wu=ev(u+v2)2
and
wv=ev·(u+v2)(ev)·2v(u+v2)2

Step 1:
To find the first partial derivatives of the function, w=evu+v2, with respect to u and v, we can proceed as follows:
First, let's find the partial derivative of w with respect to u, denoted as wu. To do this, we treat v as a constant and differentiate w with respect to u. Using the quotient rule, we have:
wu=(u(ev))(u+v2)(ev)(u(u+v2))(u+v2)2
The derivative of ev with respect to u is 0 since v is not a function of u. The derivative of u+v2 with respect to u is simply 1. Simplifying the expression, we get:
wu=ev(u+v2)2
Step 2:
Now, let's find the partial derivative of w with respect to v, denoted as wv. This time, we treat u as a constant and differentiate w with respect to v. Again, using the quotient rule, we have:
wv=(ev)(v(u+v2))(v(ev))(u+v2)(u+v2)2
The derivative of u+v2 with respect to v is simply 2v. The derivative of ev with respect to v is ev. Simplifying the expression further, we get:
wv=ev(2v)(ev)(u+v2)(u+v2)2=2vev(u+v2)ev(u+v2)2
Hence, the first partial derivatives of the function are:
wu=ev(u+v2)2
wv=2vev(u+v2)ev(u+v2)2

Result:
wu=ev(u+v2)2
wv=ev(u+v22v)(u+v2)2
Solution:
wu=u(evu+v2)
To differentiate w with respect to u, we can treat v as a constant. Applying the quotient rule, we have:
wu=(v2)·0ev·1(u+v2)2=ev(u+v2)2
Now, let's find the partial derivative with respect to v:
wv=v(evu+v2)
To differentiate w with respect to v, we can treat u as a constant. Applying the quotient rule again, we get:
wv=(u+v2)·evev·2v(u+v2)2=ev(u+v22v)(u+v2)2
Therefore, the first partial derivatives are:
wu=ev(u+v2)2
wv=ev(u+v22v)(u+v2)2
