Question

find the tangent line approximation of f(x)= sin2x+cos x at (pi/2,0)

Answer 1

wts a tangent line approximation??clarify

Answer 2

that is the question.

Answer 3

pellet

Answer 4

the slope is -3

Answer 5

y = -3(x -pi/2)

Answer 6

after that i got stuck

Answer 7

now whats there 2 it after this???

Answer 8

that is the question.

Answer 9

i just found that when a draw a secant between 2 points on the curve, and keep bringing it closer and closer, it finally becomes a tangent at a particular point, and to evaluate the limiting derivative at that point is called TLE

Answer 10

i need more help than that. You have to draw a table and do some thing .. that is what i need help for in this question
