Question

find dy/dx of
sinx+2cosy=1

Answer 1

=cosx-2siny dy/dx=0
=>cosx=2siny dy/dx
=>dy/dx=cosx/2siny

Answer 2

thank you @zaibali.qasmi could you help me in one more question
e^xy=4

Answer 3

what have to do it...???derivatie..?

Answer 4

yes.

Answer 5

thenn see it..


e^xy*(1.y+xdy/dx)=0
=>ye^xy+xe^xydy/dx
=>ye^xy=-xe^xydy/dx
=>dy/dx=-y/x
