let u = x^2 let v = e^2x
du/dx = 2x dv/dx = 2e^2x
d/dx = vdu/dx + udv/dx = 2x e^2x + 2x^2e^2x
Therefore
d/dx = ...
Differentiation is the rate of change of one variable with respect to another at a point in time or space. In other words, this can be described as the slope of a curve, which is how much the curve goes u...
So here we want to eliminate one variable so we are only working with either x or y by themself, so to do this we can rearrange the first equation of x+y=1 to x= 1-y. This new equation can therefore be su...
Rearrange AB into y = mx + c format: 1) 3y = -3 - 5x 2) y = - 5/3 x - 1
Compare equation with y = mx + c
Conclude m = - 5/3
You can also deduce the y-intercept of AB is -1.
The objective of simultaeous equations is to be able to work out two unknowns by using two equations in which they are both involved. The first step is to label the equation x+y=2 as equation 1 and 4yAnswered by Keshlee C. • Maths tutor14120 Views
