select a scale and accurately draw the vector to scale in the indicated direction.

sketch a parallelogram around the vector: beginning at the tail of the vector, sketch vertical and horizontal lines; then sketch horizontal and vertical lines at the head of the vector; the sketched lines will meet to form a parallelogram.

draw the components of the vector; the components are the sides of the parallelogram; be sure to place arrowheads on these components to indicate their direction (up, down, left, right).

meaningfully label the components of the vectors with symbols to indicate which component is being represented by which side; a northward force component would be labeled Fnorth; a rightward velocity component might be labeled vx; etc.

measure the length of the sides of the parallelogram and use the scale to determine the magnitude of the components in real units; label the magnitude on the diagram.

Using trigonometry, find the x-component and the y-component for each vector. Refer to a diagram of each vector to correctly reason the sign, (+ or -), for each component.
Add up both x-components, (one from each vector), to get the x-component of the total.
Add up both y-components, (one from each vector), to get the y-component of the total.
Add the x-component of the total to the y-component of the total then use the Pythagorean theorem and trigonometry to get the size and direction of the total.

Physics,.,

The very subject that troubles me in my second year. This subject almost got me expelled from this school. Of all the subjects I've taken in my 2nd year, I fear it most. Nothing is scarier than its horrific formulas, rules written by MAD scientists, etc.
Now I'm studying 3rd yr. physics, I expect that it will be a harder, scarier and deadlier than my 2nd yr but I promise to study harder in order to attain what is needed for me to pass the subject. I expect also that with a new teacher, I'll be able to understand each and every lesson in this class.

My 1st and 2nd week in the P6 lab...

Everythings fine. No hard topics yet. We just discussed about simple thigs like SOH CAH TOA, which is all about SIN, COS, TAN. It's also a topic in Trigonometry which discuss all about triangles. SOH CAH TOA is used in getting mssing sides and/or angles of a certain triangle. We used this while discussing vector addition. In vector addition we studied on how to add vectors. Example, you were given 3 vectors, each connected to each other, you need to find the resultant vector using SOH CAH TOA. It's like playing "connect the dots" only, it has measurement, teta(s), and much more.

That's our very 1st topic, I'm glad that I survived up to now.

3rd and 4th week in the p6 lab...

Here comes the horrors that I've been expecting. Our topic now is WAVES. OoOoh, scAry. No, seriously, it is. When I hear the formula for wave, my knees goes weak, I stutter and I just want to hide under my bed. You think its funny? Well if you're laughing right now maybe you haven't encounter this horror yet. It will squeeze you brain out of you head, makes you feel feverish and it could be a cause of stress. But as time pass by, I get to more about it, learning its weakness, the techniques I need to enhance in order to defeat this beast and get a perfect score in every quiz.

Right now I'm already struggling. Surprised with all those hardships but I will keep on fighting until there's a drop of blood in my veins and a brain to squeeze in my head.
