Best ResponseYou've already chosen the best response.2this is the same as "find the equation of the line tangent to the graph of \(y=\sin(3x)\) at \((0,0)\)"

Best ResponseYou've already chosen the best response.2take the derivative, replace \(x\) by 0 for the slope (you will get 3) and then use the point slope formula

Best ResponseYou've already chosen the best response.2since the point is \((0,0)\) the equation of the line will be \(y=3x\)

Best ResponseYou've already chosen the best response.0ok so find the derivative of sin 3x right?

Best ResponseYou've already chosen the best response.2yes now evaluate at \(x=0\) to find your slope

Best ResponseYou've already chosen the best response.2that is the slope of your line

Best ResponseYou've already chosen the best response.0okay so now i have to use the point slop formula?

Best ResponseYou've already chosen the best response.2but the point is \((0,0)\) so it is just \(y=3x\)

Best ResponseYou've already chosen the best response.0linear approximation of f(x) at x=x0: \[f(x)=f(x_0)+(xx_0)f'(x_0)\]

Best ResponseYou've already chosen the best response.0you can use this way too. (notice the resemblance to equation of line)
