i know the answer which is -√(36-x^2)/36x+C

Homework Statement integral (1)/(x^2sqrt(36-x^2) Homework Equations The Attempt at a Solution I found X=6sinθ dx=6cos √(36-x^2)=√(36-sin^2θ)=6cosθ i think the problem is that i am not getting integral of ∫csc^2θ

so what is gne be net force using the coulombs law... Fq2 to 3 =(9*10^9)(3.5nC)(5.0nC)/-0.4^2 Fq1 to 3 = (9*10^9)( -2.5nC)(5.0nC)/-0.6^2

Homework Statement Two point charges are located on the y-axis as follows: charge q1=-2.5nC at y=-0.6m, and charge q2=+3.5nC at the origin. What is the net force (x, y components) exerted by these two charges on a third charge q3=+5.0nC located at y=-0.4m? Homework Equations F=k...

how many inverter I wud hve to use...little confusing I guess

Homework Statement How to make a logic gates only using NAND gates of the following diagram. How many NAND gates I would have to use for that diagram Homework Equations The Attempt at a Solution I know that A bar bar + B bar bar =AB A bar bar B bar bar = A+B De-morgans Theorem
