Thus, we see that the
Keep in mind that . You will also need to apply the product rule to the term.Find the derivative and simplify:
2) y = (x)(arccosx) - (1-x^2)^(1/2)
Keep in mind that3) y = arctan(x-(1+x^2)^(1/2))
Again, keep in mind that , but recall that4) y = arctan (x/9) + ln( ( (x-9)/(x+9) ) ^ (1/2) )
and find the limit of
5) Lim as x goes to 0 from the right, arctan(lnx)
Any help would be very much-ly received and appreciated!!
Note that as ,
In essence, we are finding
This is the same thing as asking what value of theta causes ?
I'll let you think about that.
I hope this helps!
