Open the brackets. You then have three separate integrals. The first ∫ x 2 d x is simple and equal to 3 x 3 . The second ∫ tan 2 x d x is also simple if you remember that d x d (t a n x) = 1 + tan 2 x

lim_(x rarr 0)tan^2x/x = 0 lim_(x rarr 0)tan^2x/x = lim_(x rarr 0)(tanxtanx)/x :. lim_(x rarr 0)tan^2x/x = lim_(x rarr 0)sinx/cosx * sinx/cosx *1/x :. lim_(x rarr 0 If x is supposed as a Positive or negative integer as the case might be and such that it lies b/w 0 and 90(less than 90) when doubled then the value of this angle in tangent is the value or the answer of your question Here is our post dealing with how to differentiate tan^2(x). The chain rule is useful for finding the derivative of a function which could have been differentiated had it been in x, but it is in the form of another expression which could also be differentiated if it stood on its own.

tan 4x We know that tan 2x = (2 𝑡𝑎𝑛⁡𝑥)/(1 − 𝑡𝑎𝑛2 𝑥) Replacing x with 2x tan (2 × 2x) = (2 𝑡𝑎𝑛⁡2𝑥)/(1 − 𝑡𝑎𝑛2 2𝑥) tan 4x = (2 𝑡𝑎𝑛⁡2𝑥)/(1 − 𝑡𝑎𝑛2 2𝑥) = (2 ta 2009-08-15 · Nayan, I don't understand what you didT_T I can see you used the trig identity for sec^2 x but that's not what confuses me. I just don't know how to actually do the subtracting 2010-06-16 · you will get a discontinuity for any fee of x (the self sufficient variable) that makes the denominator 0, or if it ends up in some thing that's undefined. as a effect e^(a million/x) = -a million if denominator is 0 fixing this rsults in Ln(-a million) that's undefined. for this reason the function has a hollow at x = 0 and is as a effect discontinuous there. integrate x/(x-1) integrate x sin(x^2) integrate x sqrt(1-sqrt(x)) integrate x/(x+1)^3 from 0 to infinity; integrate 1/(cos(x)+2) from 0 to 2pi; integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi; View more examples » Access instant learning tools.
