Differentiate the function. f(x) = sin(x) ln(2x)

math
nevermind, all figured out. thanks!

oops, yes carrot cakes...typed too fast. still dont understand, can you explain it better for me please?

castor brought 6 3/4 carat cakes to share with 26 students. did castor bring enough for each student to have 1/4 of cake?

Use Newton's method with the specified initial approximation x1 to find x3, the third approximation to the root of the given equation. (Round your answer to four decimal places.) 1/3x^3 + 1/2x^2 + 1 = 0, x_1 = −3

Cal 1
Verify the given linear approximation at a = 0. Then determine the values of x for which the linear approximation is accurate to within 0.1. (Enter your answer using interval notation. Round your answer to two decimal places.) tan x ≈ x

Cal 1
Verify the given linear approximation at a = 0. Then determine the values of x for which the linear approximation is accurate to within 0.1. (Enter your answer using interval notation. Round your answers to three decimal places.) (1 + 2x)^1/4 ≈ 1 + 1/2x

Cal 1
Find the linearization L(x) of the function at a. f(x) = x^4/5, a = 32
