Coefficients can be removed when differentiating, i.e. d/dx 2tanx = 2 d/dx tanx
You should know that d/dx tanx = sec2x (either by differentiating sinx/cosx or by just remembering the derivatives of common trig functions, as it will come in handy).
So the answer is 2sec2x
For a number in form af(x) while differentiating with dont interfere with the constant a.
So, it is a d(f(x))/dx
Here assuming were differentiating with respect to x,
we have 2*d(tan x)/dx
From here you have options weather you can differentiate ie based on uv or u/v method. I'll be using u/v (easy to apply for division),
Here's the general form,
(u/v)' = {vu' - uv'}/v^2
d(tan x)/dx =d(sinx/cosx )/dx = {cosx(sinx)' - sinx(cosx)'}/(cos^2)
= {(cos^2 x) - (-sin^2x)}/cos^2 = {(cos^2 x) +(sin^2x)}/cos^2
Since sin^2 x + cos^2 x =1 ,
we have
d(tan x)/dx = 1/cos^2x = sec ^2 x.
Therefore the final answer for,
2d(tan x)/dx = 2sec^2 x

log 3 is a constant, so d/dx log3, like d/dx of any constant, equals zero.
The open channel flow has a free surface whereas the pipe flow has a closed surface.
The derivative of the ln function is the function 1/x. So the derivative of ln1.01 should be 1/1.01 = 0.990099... ------------------------- Well I may be looking at this slightly different, but the question as stated "differentiate ln(1.01)" would be 0 seeing as ln(1.01) is itself a constant (irrational) number. The derivative of any constant is zero. If the intended question was ln(x)d/dx where x=1.01 then I agree with the above answer.
tan(2x) = 2tanx/(1 - tan2x) So tan(2x) +1 = 2tanx/(1 - tan2x) + 1 = 2tanx/(1 - tan2x) + (1 - tan2x)/(1 - tan2x) = (-tan2x + 2tanx + 1)/(1 - tan2x)
I assume you mean (tanx+1)^2 In which case, (tanx+1)^2=tan2x+2tanx+1
