Cos(a-b) can be given as, cos (a - b) = cos a cos b + sin a sin b, where 'a' and 'b' are angles. What is the Formula of Cos(a-b)? The cos(a-b) formula is used to express the cosine compound angle formula in terms of sine and cosine of individual angles. cos(a-...
The cosine formulas talk about the cosine (cos) function. Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" ...
What is the exact value of sin 5pi/2? What is the exact value of sin (285^o)? What is the exact value of sin 45 degrees using the half-angle formula? If \sin A = \frac{1}{3}, what is the value of \cos A? If u(t) = \langle \sin 5t, \cos 5t, t\rangle and v(t...

The power factor formula is given as The power factor in ac circuit cosϕ = VIcosϕVI kWkVA Active PowerApparent Power i.e., the power factor of the circuit can also be defined as the ratio of active power (kW) to the apparent power (kVA) 3. Reactive power (kVAR) = Apparent ...
Otherwise, you’ll have different figures for the same type of sale, which makes it harder to base decisions on COS. Retail business example So, what’s the cost of sales for a retail business? The owner of a homeware store applies the cost of sales formula for a new item – ...
There is one story about him which is a bit quirky, but it's probably not true. The story goes that the queen was being bothered by an atheist who was influencing people at court. She called on Euler to call him out and Euler announced that he had discovered a formula that proved tha...
cos θ = $\frac{AM}{AP}$ tan θ = $\frac{PM}{AM}$ It is evident from Δ AMP that as θ becomes smaller and smaller line segment Pm also becomes smaller and smaller and finally when θ becomes 0o, the point P will coincide with M. Consequently, we have, ...
