Question

lim 2-cos3x-cos4x/x
x>0
using squeezing theorem

Answer 1

Is this question? \[\lim_{x \rightarrow 0}\frac{2-cos3x-cos4x}{x}\]

Answer 2

hey r u there..

Answer 3

@Callisto
yup i agree with ur question

Answer 4

use ...
2-cos3x-cos4x=(1-co3x)+(1-cos4x)= 2(sin3x/2)^2 +2 (sin2x)^2

Answer 5

callisto : yes, it is .

Answer 6

how it can be like that, @matricked ? 2(sin3x/2)^2+2(sin2x)^2 ??
