Hello my fellow mathematicians,
I joined the forum today, and I hope to integrate well with this forum. I love science subjects and have made an attempt in doing Biology, Physics, Chemistry and Maths.
I'am in urgent need for help in Mathematics as my college midterm exams are getting nearer (12 days left). I intend on using this thread for posting questions that have significantly hindered my progress:
Differentiating exponentials and logarithms:
Q1, Given that y = 5/1+e^3x, find the value of dy/dx when x = 0.
Q2,Defferentiate each of the following functions with respect to x.
d, ln 2x+1/3x-1
Solve the equation sin2@ = 4sin(@-60), show that 2 . 3cos@ = sin@. Hence find the value of @ such that 0<@<360.
Correct. By the way, how do you write the whole thing like that. MS word does not have mathematical syntax.I assume that you mean:
Alright thanks for the help, but I have trouble understanding the chain rule used here. Oh and can this:
be used with the chain rule together? I always thought they were seperately done. Oh and please can someone tell me the solution to the Trignometry problem.
Sure thing. I'll keep that in mind.Don't do that, rather post one question per thread. Otherwise the thread will become unweildy and difficult to follow/make sense of.
I'm going to demonstrate b):
der. outer fct. means derivation of the outer function
