Be the first one to answer
hey are you solving integration by parts but all the way answer is d(uv)/dx = f(x) g , (x) + g(x) f , (x)
dear student, ques is not proper
what is this KPS
f’(x)g(x)+g’(x)f(x)
the expression could be written as 1-2cos^2(x).sin^2(x) so here it is repeating afer pie thus the interval is pie approve if useful
I think that the question is incomplete.
for first question apply L’ Hopitol rule second question is not clear
When the rate is varying...
Arihant Publications’s Differntial and Integral Calculuc..by A M Aggarwal..
ok , u can use property of log and can write it as log5/logx now log5 is constant and u have to diffferentiate 1/logx wrt x and the answer is 1/x (logx) 2 APPROVE IF USEFUL
f(x) is odd means f(-x) = -f(x) so, f(0) = -f(0) or, f(0) = 0 its period is 2 so f(0) = f(2) = f(4) = 0
=4
you can diffrentiate then in two ways first column wise and second row wise method row wise diffrentiate first row while seepind other 2 rows constant+ diffrentiate second row keeping other 2 constant...
you can solve the given question by using lhospital very useful and time saving rather series expansion 0/0 form is obtained diffrentiate until you are out of the form finally put x=0 the answer will...
sorry i ain’t mentioned about the 0/0 form it might be and given indeterminant out of those 7 indeterminate forms but we first have to convet the given value into 0/0 form
l’hospital rule is used to calculate the value of the funcions having limits attached to them there first of all we get the 0/0 form and then we diffrentiate the numerator and denominator untill and...
the answer comes to be a very little -1
DONT FORGET TO APPROVE IF USEFUL!!!!
Put x=coso in sec -1 [1/2x 2 -1] then u get 2o put again o=cos -1 x then diff with respect to x......1 similarly put x=coso in [1-x 2 ] ½ u get sino put again o=cos -1 x then diff with...
again an implicit function first take log both sides mlnx+nlny=m+nln(x+y) now diffrentiate both sides you will get the answer y/x approve if useful
i would say that it is an implicit function 1 st @x=0 calculate the value of y which is equal to 1 now diffrentiate both left and right hand side the then substitute the values 0,1 the answer is equal...
2(3) 1/2 is the correct
