Use quotient rule to differentiate:

dy/dx = (18x(3x+2) - 3(9x²+1))/(3x+2)²

set dy/dx=0:

54x² + 36x - 27x² - 3 = 0

9x² + 1...

This can be done by taking moments. To reduce the number of equations a moment should  be taken so that one of the forces goes through the centre of place from which moments are being taken. We will choos...

2,4,8,16,32 The series is multiplying by two every time.

Going through the checklist: B= Brackets (there are no brackets) I=Indices (there are no powers) D= Division (there is no division) M= Multiplication. we have a times sign in this problem between the 3 an...

Analyse the integral, common functions in which integration by parts is the best method include lnx and polynomials of x multiplied by exponential functions or sine and cosine functions. If this is the ca...
