    Calculating the resultant force using vector

    So you have: Forces in Y: 500N, 1000N The force that act at a certain degree should be expressed in Y and X components: If the wind of 300 N comes from below at 45 degree angle: X component of the 300 N force: 300 x cos (45) = xxx N Y component of the 300 N force: 300 x sin (45) =...

    How Do You Find the Equation for Sine and Cosine from a Graph?

    Just to make myself clear that that the period has been tretched ( i know you could clearly see from the graph ) but it just help me rember :)

    How Do You Find the Equation for Sine and Cosine from a Graph?

    Thanks: Equation for Sine: 2 sin(1(x-2)) Now i finally understand how to find the equation for Sine Im now trying to find the equation for Cosine I'll give it a try first. i'll post when I'm stuck :) thx!

    How Do You Find the Equation for Sine and Cosine from a Graph?

    Im trying to find the equation of the green one. the pink one is just Sin(x). Green ( one period or 2 phi ) : 2 sin(1(x - 2) ?! is this right?

    How Do You Find the Equation for Sine and Cosine from a Graph?

    a = 2 d = 0 b = period remain the same = 2 phi c = ... since the graph is shifted to the right, means that it should be -c not +c c = -2 ?!?
