If ya meant pi as in π

π is defined as the ratio between the circumference and diameter of any circle

the definition of pi is $\pi=\frac{circumference}{diameter}$

I'm sure you mean π (pronounce as "pie" and spelled as "Pi"), the sixteenth letter of the Greek alphabet. π is the ratio between a circle's circumference and it's diameter.

F(x)=3/x+2-√x-3 f(7)=

Paladinen [302]

Divide each term by x and simplify.

(Ok so I don’t make it confusing the first part after “F=“ will be on top The I’ll put the bottom part below oh btw the top and bottom r negative so put the negative sign in front of the fraction)

F= - 21fx+x√x-2x-3(top of fraction)

F=-x^2(bottom of fraction)

The point (1,-1) is on the terminal side of angle theta in standard position what are the values of sine cuisine and tangent of

pickupchik [31]

$\bf \textit{terminal point }\implies 
\begin{array}{lclcll}
(&1&,&-1)\\
&\uparrow &&\uparrow \\
&x&&y
\end{array}
\\\\\\
sin(\theta)=\cfrac{y}{r}
\qquad 
% cosine
cos(\theta)=\cfrac{x}{r}
\qquad 
% tangent
tan(\theta)=\cfrac{y}{x}\\\\
-----------------------------\\\\
\textit{so, what's the radius "r"?}\implies r^2=x^2+y^2\implies r=\sqrt{x^2+y^2}$
