Actually in my school exams we are not allowed to use l'hospital rule we can use it only in competitve exams
.
Let me try to make u understand
I am saying that i separated tanx term and sine x term
Now i multiplied and divided tan term with tan^2x and sin with si^2x
Then i combine tan^3x...
Homework Statement
there is one question
limx--->0tanx-sinx/x3
i actually tried to seprate tanx and sinx amd then i multiplied and divided by tan2x and sin2x so that i can make tan3x/x3and sin3x/x3 to be 1 and in the end sin2x canceled and i got the answer as -1 which is wrong
what errror...
