I've got tons of experience tutoring students of all ages, and I enjoy teaching Math and making videos. My videos are enjoyable, and I make sure to show how all those math problems relate to real-life situations.
If $f(x)=x+\sqrt{2-x}$ and $g(u)=u+\sqrt{2-u},$ is it true that $f=g ?$
Odd functions If an odd function $g(x)$ has a local minimum value at $x=c$ , can anything be said about the value of $g$ at $x=-c$ ? Give reasons for your answer.
Sketch the domain of the function.$h(x, t)=\frac{1}{x+t}$
In the following exercises, find the radius of convergence $R$ and interval of convergence for $\sum a_{n} x^{n}$ with the given coefficients $a_{n}$$$\sum_{n=1}^{\infty} \frac{(2 x)^{n}}{n}$$
Let $A, B,$ and $C$ be sets. Use the identities in Table 1 to show that $\overline{(A \cup B)} \cap \overline{(B \cup C)} \cap \overline{(A \cup C)}=\overline{A} \cap \overline{B} \cap \overline{C}$
Find the points where the tangent line to the curve y=3x2?x3 is horizontal
A statue is to be placed in the center of the park. The area of the base of the statue is 4x 2 + 12x + 9 m2. Factor the area to find the lengths of the sides of the statue.

(a) Find the position vector of a particle that has the givenacceleration and the specified initial velocity and position.a(t) = 18t i + sin t j +cos 2t k, v(0)= i, r(0) = j
Determine the velocity vector r(t) of the path r(t) = (cos^2(3t), 6t−t^5, −9t).
2. Determine the equation of the tangent line to the path r(t) = (sin(3t), cos(3t), 8t^(7/8)) at t = 1.
3. Suppose that a particle following the path c(t) = (t^2, t^3−5t, 0) flies off on a tangent at t₀ = 4. Compute the position of the particle at the time t₁ = 6.
