I can provide good answers to questions dealing in almost all of mathematics especially from A`Level downwards. I believe i would be very helpful in calculus and can as well help a good deal in Physics with most emphasis directed towards mechanics.
An engineering graduate. I have been doing maths and physics all my life.

Hi Patti, In the first scheme, the pay in dollars P1= 1000 + 20h where h is the number of hours worked. In the second P2 = 25h Now, for P1 < P2
Hi Kevin, For a quadratic form x² + kx, we complete the square by adding (k/2)² and then factorising as (x - k/2)². So, for f(x) = x² - 6x + 14 f(x) = x² - 6x + 3² - 3² + 14 = (x² - 6x + 9) + (14 -
Hi Abirami, x² + 4xy - y² = 8 Differentiating with respect to x 2x + 4(xy' + y) - 2yy' = 0 2x + 4xy' + 4y - 2yy' = 0 2x + 4y = 2yy' - 4xy' x + 2y = yy' - 2xy' y' = (x + 2y)/(y - 2x) To find y''
Hi Kristen, S(x) = ln(x+2) D(x) = 10 - ln(x+1) There is market equilibrium when S(x) = D(x), i.e ln(x+2) = 10 - ln(x+1) ln(x+2) + ln(x+1) = 10 ln[(x+2)(x+1)] = 10 (x+2)(x+1) = e^10 x² + 3x + 2
Hi Shameem, By squaring both sides you get abs(x) = (x+5)²/36 You need to realise here that; abs(x) = x for x > 0 and abs(x) = -x for x < 0 You therefore solve the equations; x = (x+5)²/36 (remembering
