Question

Write the equation for the differential, written dy, for y = sec (5x).Simplify, where possible.

Answer 1

1) Differentiate y=sec 5x in the usual way.
2) Multiply both sides of the resulting equation by dx.

Answer 2

could you show me how?

Answer 3

\[\frac{ dy }{ dx } = \frac{ d }{ dx }(\sec5x)\]
\[\sec5x*\tan5x*\frac{ d }{ dx }(5x)\]
hope u can do it now

Answer 4

would the answer be dy=5y tan(5x)dx?

Answer 5

yeah
