Constant colinear force: W = F x x = distance traveled. 2. Constant non-colinear force: W = F • Δr = F Δr cos θ = Fx Δx +  A joule, in terms of fundamental units, is easily calculated: W = Fx = (m) = The joule is a multipurpose unit. It serves not only as a unit of work, but also of energy. 30 Mar 2017 Principle 1- work over a closed loop W = Fx.cos(q) W(up) = mgh.cos(180) = -mgh W(down) =mgh.cos(0) = mgh Total Work = -mgh + mgh = 0; 11  Yes it is possible but it depends that on which direction f component is acting . Cos theta = base / hypotenuse . Hope it is clear . There are several examples 

Evaluate Units with cos Function. cos numerically evaluates these units automatically: radian , degree , arcmin 

Why does one need a cos and theta when we can easily get the work by matter because the y component is going vertical and doesn't do anything to with the  The diagram shows the graph of f(x) = sin x + 2 cos x. Amazingly it looks like an ordinary sine wave that has been translated to one side and with an amplitude 

31. The angle θ is measured counter clockwise from the +ve x-direction. So if θ=0, then the force is acting in the +ve x-direction. If θ=180, then the force is acting in the -ve x-direction. (This is why in the case of friction θ=180). If θ=90, then the force is acting perpendicular to the mass it is acting on.

function f(x) is plotted along with its tangent line at x = a. Notice how Solution Here 62◦ is close to 60◦ which is π/3 radians, and we know cos(π/3) = 1/2. Letting. functions and W is a space of trigonometric polynomials. sin(kt) and cos(kt), 1 ≤ k ≤ m constitute an orthogonal basis for Tm. Let f(x) be the sign–function. If the function f(x) is defined on the interval [a,b], then its Fourier series representation is given by the same formula. f(x)=a02 + ∞∑n=1(ancosnπxL+bn sinnπxL). cos(x) Cosine function: f(x) = cos(x) It is an even function. But an even exponent does not always make an even function, for example (x+1)2 is not an even  Evaluate Units with cos Function. cos numerically evaluates these units automatically: radian , degree , arcmin  This theorem bridges the antiderivative concept with the area problem. Indeed cos(t2)dt . From the Fundamental Theorem of Calculus, we know that F(x) is an 

cos(t. = f='o -1 (2n)!s4n+l·. 12. Given that Q(s) is a polynomial with n distinct zeros, we may conditions are that for both u(x,y) and f(x,y) all first partial derivatives.

W = f x d x cos(0 ). W = f x d x 1. W = f x d. For perpendicular force and displacement the angle is 90 . The cosine of 90 is 0, which would make work equal 

The definition of a DOT product! -Dot product finds component of one vector in the direction of the other, then multiplies the two. -Dot product “projects” one vector on to the other, then multiplies the projection and the vector.
