(a) Asks to differentiate an equation C: 4x² - y³ - 4xy + 2^y = 0Then use the fact that point P (-2,4), lies on C to find an expression for dy/dx Differential of form 8x - ...

In order to solve this, we need to bring all of the x values to one side, we can do this by subtracting the 2x from both sides7x + 6 - 2x > 1 + 2x - 2x5x + 6 > 1 We then need to move the values onto...

Simplify 48^1/2 :48^1/2=(124)^1/2=(434)^1/2=(4)^1/2(4)^1/2(3)^1/2=22*(3)^1/2=4(3)^1/2

i) 3Z-4WFor this question it is just the matter of substituting the complex numbers of Z and W into the equation. So, 3(4+3i)-4(6-i). Then multiply out the brackets to get 12+9i-24+4i. Finally simply to g...

87°.
This is because there are 3 angles and 180° in a triangle.
180°- 60°- 33° = 87...
