What is the ratio of sides of a right triangle for each of the trig functions: sin, cos, and tan?
The ratio of sides of a right triangle for each of the trig functions are the following: sin = opposite/hypotenuse cos = adjacent/hypotenuse tan = opposite/adjacent *note: Opposite means the side directly across from the angle you are looking at. Adjacent means one of the connecting sides that makes the angle you are looking at, but it is not the hypotenuse. Hypotenuse means the longest side, the one that is usually at a slant and doesn't make the right angle.
What are some general writing tips I should remember when writing a paper for a literature class?
Some general tips that you should keep in mind when writing a literary paper include the following: (1) Grammar and punctuation are important in the world of literature, so make sure you have well formulated sentences and correct punctuation. If you are unsure, google what kind of punctuation or grammar should be used. (2) Read your paper back to yourself out loud. This will make any grammar mistakes or choppy sentences stick out so you can easily find and fix them. (3) Have someone else read over your paper. This will allow you to see if your paper makes sense.
How does diffusion through a cell work?
Diffusion is the passive process where substances move from areas of high concentration to areas of low concentration. So, for example, there are water molecules within a cell. If there are more water molecules outside of the cell than inside the cell, then water molecules with diffuse (move from the high concentration to the low concentration) through the semi-permeable cell wall that surround the contents of the cell. This will create a balance known as equilibrium and while the exchange of water molecules will still occur across the cell membrane, the cell and its surrounding will remain in equilibrium and diffusion will no longer be an occurring process.
