The first one is correct.
Can't read the second one. But we eat pie and is the number pi. Try using LaTeX.
Third one: if then .
Ok so I am new to calculus and have come up to 3 questions in my book that I am not sure... Could someone help!
lim (x/x)
x→0
lim f(t) where f(t) = sin^2 (pie t), t < -2
x→-2 2t-4, t >= -2
lim ((1/x)-(1/|x|))
x→0+
For now I have 1 for the first one and does not exist for the other two...Can anyone confirm please?
