hi guys, I thought I knew how to solve these sorts of problems but i keep getting the wrong answer. Please help me see where I'm going wrong. So, the question asks me to find the equation of any tangent lines to the curve x^4-12x+50 that pass through the point (0,2). I start by finding the...

Ah perfect, thank you. I'm happy now. So why call the line a tangent if it intersects the curve in two places? Wouldn't that make it a secant?

i eventually got it. thanks. Can I ask a supplementary question from the same set - "find the point(s) on the curve y=x^2 at which the tangent line is passing through the point (2, -12)" So since (2,-12) is not on the curve, I guess this is asking me to work out where the tangent line comes...

Hello, I'm looking at Mendelson's "Beginning Calculus" and having real trouble making sense of this question. "For each function f and argument x = a below, find the slope-intercept equation of the tangent line corresponding to the given argument a." The function is : f(x) = 2x^2 + x...

Let's say you have a function in which you have a linear function divided by a parabola. How do you find the range of this? Also, how do you find the range when you have something such as a parabola divided by a parabola? Thanks for your help.

Thank you - I had come across the khan academy when trying to get help with maths problems. I'll look into it further. :)

G'day. I want to study a BSc next year, and this year I am doing the UPC in Maths and Science. These start in a few weeks and since I did poorly in the HSC and did no senior level science, I have been studying year 10 level textbooks to try and get a head start for this year. I am...
