Frictional force acting:FMax= uR = 0.7 x 5 x 9.81 x cos(30) FMax = 29.7NWeight acting down the slope:F = 5 x 9.81 x sin(30)F = 24.5NFric...
This question is split up into two parts.Firstly recall the trigonometric identities you know, the trick here is to eliminate one of the squared terms. Using 4sin^2(x) +4cos^2(x) = 4, the cos term i...
The rule for differentiating a simple equation such as this is, to times the coefficient by the power and the take one away from the power. Therefore, lets look at 5x^4 you would times the 5 by 4 to get 2...
2x + 5y = 11
This equals to dy/dx= 1/3 x2+1/3 x1This is because we divide by the power and then minus one from the powerSo it becomes x3-1/3 which can be simplified to 1/3 x2VIAnswered by Vera I. • Maths tutor3163 Views
