If f(2)=3 and f (2)=5, find an equation of 1. the tangent line and 2. the normal line to the graph of y=f(x) at the point where x=2.
Explanation would be greatly appreciated!-1) tangent line
general
I really need help with that one ! And this one !!
My number has two digits , and both digits are even
The sum of digits is 10-I think that these are all for one answer
a number that is divided by
{(-4, -1), (-2, -9), (1, 3), (7, 5)}
FIRST BEST ANSWER GETS 5 STARS -Yes, because no two ys are matched with one x. Because then you would have two points for the same x, which fails the vertical lin
I need help with these problems... :/
The limit as x approaches -3 of (t^2-9)/(2x^2+7x+3) (I mostly need help with factoring the bottom...)
The limit as x approaches -2 of (x+2)/(x^3+8) (once again,
No matter how much practice I get, or how much I work on them, I just. cant. do word problems! Trust me, I HAVE practiced them many many many times. And I still struggle a lotttt. Im lucky if I can ev
If 3^(x+2) =18, then 3^x = ?
I think Im thinking too much with this problem. I tried solving it by doing the log thing were you switch 18 and (x+2).The problem would look like this
3^18=x+2
That is
Please show the steps if you can help,
will vote best answer shortly-y= √(x²+9)
x=√(y²+9)
x²=y²+9
y²=x²-9
y=± y= √(x²+9)?
that is the inverse functions.
y= √(x²+9)
y= - √(x²+9)
Can I use trig sub.-Yes, use a trig. substitution.
Let y = x tan t, dy = x sec^2(t) dt.
So, ∫ dy/(x^2 + y^2)^(3/2)
= ∫ (x sec^2(t) dt) / [x^2 + x^2 tan^2(t)]^(3/2)
= ∫ (x sec^2(t) dt) / [x^2 sec^2(t
You probably have seen my post about these mathematic questions? But I dont understand. And if you can explain and answer the question to me, please :)
