Graphing Calculator Use a calculator to complete a table of values for $\sin x, \cos x$, and $\tan x$, as $x$ varies from $0^{\circ}$ to $90^{\circ}$ in increments of $10^{\circ}$.
Complete this sentence: $\sin x$. from to as $x$ increases from $0^{\circ}$ to $90^{\circ}$.

a. Use a calculator to find $e^{0.5}$ (rounded to five decimal places). b. Estimate $e^{0.5}$ by using the first four terms of the Taylor series $e^{x}=1+x+\frac{x^{2}}{2 !}+\frac{x^{3}}{3 !}+\frac{x^{4}}{4 !}+\cdots$ evaluated at x = 0.5 (rounded to five decimal places). c. (Requires sequence and series operations) Set your calculator to find the sum of the series in part (b) up to any number of terms. How many terms are required for the sum (rounded to five decimal places) to agree with the value found in part (a)?

Plot the points. A(3,5),B(-2,4),C(3,0),D(0,-3).

Hydrogen and oxygen are reacted and the water formed is collected at $25^{\circ} \mathrm{C}$, where it has a density of 0.997 g/mL. If 36.8 g of $\mathrm{H}_2$ and 168g of $\mathrm{O}_2$ are reacted, how many mL of water will be collected?
