i) Using implicit differentiation find dy/dx for x^2 + y^2 = 4 ii) At what points is the tangent to the curve parallel to the y axis iii) Given the line y=x+c only intersects the circle once find c given that c is positive.

I don't know how effectively I can communicate this answer via text without the whiteboard but I'll try. i) First implicitly differentiate with respect to x: 2x + 2y * dy/dx = 0. Rearranging gives dy/dx = -x...

Solve the simultaneous equations, 2x+y-5=0 and x^2-y^2=3

2x+y-5=0, y=5-2x (put into second equation) x 2 -y 2 =3, substituting in we get, x 2 -(5-2x) 2 =3, expand, x 2 -(25+4x 2 -20x)=3, simplify, x 2 -25-4x 2 +20x=3, 0=3x 2 -20x+28, put into brackets by seperatin...
