Haha.. Me tooI didn't get it.
are they correct..
haha . Look if two vectors are collinear of parallel then they have a common ratio between them . suppose a=(2.4.6) and b=(1.2.3)
a/b =2 and so they are both collinear
You are welcome, I am glad I did something to help you!!Thank you Thank you Thank you!
I got it.
You are welcome, I am glad I did something to help you!!
Btw, ._. can you explain? like some steps are so weird to me.

many but none with s2How many accel people are here..?
yeah that's correct too but that is kind of a solving the whole thing type method..... what he said is much simplar....OR... Their unit vectors are equal.
sory i was out.. wat was ur question??many but none with s2
OOOOhhh, Jazaki Allah Soooooooooo muuuchhhh!! Thank youuuuuuuuuuuu!!!!!!!!!!!!I = ⌡(tanⁿ⁺² x + tanⁿ x) dx
Break tanⁿ⁺² x into tanⁿx* tan²x
I = ⌡( tanⁿx* tan²x + tanⁿ x) dx
I = ⌡( tanⁿx ( tan²x +1) sec²x
tan²x +1 = sec²x
I = ⌡( tanⁿxsec²x) dx
u = tan x
du = sec²x dx
dx = 1/sec²x du
Substitute tan x = u
I = ⌡ uⁿ xsec²x) *1/sec²x du
sec²x gets canceled.
I =⌡ uⁿ du
I = uⁿ⁺¹/(n + 1)
Change the limit of x for u and solve. Hope this helps.
