Im in AP calculus B/C if it affects your answer at all
and if I'm not mistaken
limit sin(x)/x = 1
x-> 0
and
limit sin^2(x)/x^2 = 1
x-> 0
but how would i go about seperating the the 1+cos(x) from the denominator
could i make the function
limit...
Homework Statement
Lim (1-cosX)/X^2
X->0
Homework Equations
Not 100% sure try to use the following identity:
sin^2(X)=(1-cosX)(1+cosX) or
sin^2(X)=1-cos^2(X)
The Attempt at a Solution
Tried substituting (sin^2(X))/(1+cosX)) for 1-cosX but that didnt help and so for the last half...
