Thanks :)

Any more estimates for accuracy?

Wow :o thanks

How did you get (1/ln10) (1/x)? I know when lnx gets differentiated it becomes 1/x but what about (1/ln10)?

Another one... Differentiate log10X 10 is the base

Need help with this question; Find the area enclosed between the curve y= sqrt (4-x^2) and the line x-y+2 = 0. I've taken the area of a circle formula into consideration this time.

Ohh I get it now. Thanks a lot guys.

Find the area bounded by the curve y= sqrt(4-x^2), the x-axis and the y-axis in the first quadrant. Thanks

You should make one for science subjects too :D

Does that help? 8x^2

I was never aware of the rule tan(same)/same = 1. Thanks for clarifying it Panda!

Can't seem to solve this question :/. Any help will be greatly appreciated.

To see rest of the question click on reply with quote, this is quite annoying

Seems like the topic at the moment is the same as mine so I'll ask a question of mine here; Find the points of intersection of the curves y=sin theta and y=cos theta for 0<pi<2pi and calculate the area between the two curves.

Walaykum Salaam, thanks for the answer mate :)
