Question

Differentiate the following function.
h (θ) = 7 sec(θ) + 4 eθ cot(θ)

Answer 1

this is what i got...\[7(\sec \theta \tan \theta)+4(e ^{\theta} \cot \theta -\csc ^{2}\theta)\]

Answer 2

\[dh/d \theta=7\sec \theta \tan \theta-4e^\theta\csc \theta \cot \theta-4e^\theta \csc \theta\]

Answer 3

oops my last part was wrong

Answer 4

whats wrong with mine?

Answer 5

your looks fine...one sec...lemme double check

Answer 6

webassign is telling me its wrong

Answer 7

it is...i see what u did wrong

Answer 8

the last part is -e^(theta)csc^2(theta))

Answer 9

by chain rule

Answer 10

so its 4(-e^theta csc^2(theta))??

Answer 11

7(secθtanθ)+4(eθcotθ−(*(e^(theta))*)csc2θ

Answer 12

take all the parenthesis out...that starred area is what u needed to add...

Answer 13

u get it?
