The Curve C shows parametric equations x = 4tant and y = 5((3)^1/2)(sin2t) , Point P is located at (4(3)^1/2, 15/2) Find dy/dx at P.

First I would find the value of t at Point P - I would equate the x equation to 4(3)^1/2 and the y equation to 15/2. This would give me (Px,Py). After this I would then find dy/dt, and dx/dx by differentiati...

Solve the simultaneous equations, x+y = 16, 5x -2y = 17

Multiply the first equation by 2 to obtain 2x+2y = 32,Then use the elimination technique and add the first equation into the second equation to get : 7x = 49 therefore divide by 7 to find x = 7 Sub this valu...
