How Do U Find The Tangent Of This??
i really don't understand what to do...
it says to determine the equation of the tangen to the curve
y= 1/x at the point on the curve where x=2 ?????
and then the following question is like to find the equation of the tangent to y=x^2 -2y+5=0 which is perpendicular to the line x-2y+5=0
????? how do u do it wen u hav to hav find it perpendicular to that
Please Tell Me If Im Doing This Right Or Not
so u said to take the derivative and plug the number in...and then use the slope formula....please tell me im doing it the right way
m=(-1/4 - y)/(2-x)
m*(2-1)=(-1/4 - y)
what do i do from here?
