Find the derivative of f (x comma y )equals x squared plus y squared in the direction of the unit tangent vector of the curve bold r (t )equals (bold cos font size decreased by 2 t plus t font size decreased by 2 bold sin font size decreased by 2 t )bold i plus (bold sin font size decreased by 2 t minus t font size decreased by 2 bold cos font size decreased by 2 t )bold j, t greater than 0.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

a
