The formula for sin.(α + β) (EWD1244a)The above describes what WLOG (= Without Loss Of Generality) is usually about. In principle—as shown above—the technique is perfectly sound, but the problem is that in practice it is only too often appealed to by the mere "WLOG we can ...
The formula for a function y=f(x)=6x4,x<0. Find a formula for f−1(x) Inverse using Radicals: The basic rule to obtain an inverse function is to exchange the variables of the given function and simplify the obtained expression for variable y. Use the ra...
Question: Derive a formula for sin(θ2) using only trig functions ofθ. Half-Angle formula: We called half-angle formula to the trigonometrical relation below: cos(2θ)=cos2θ−sin2θ=1−2sin2θ Answer and Explanation:1 ...
If we directly pass the angle to SIN in the Excel function, it will not recognize it as a valid argument. So, for example, if we give 30° as the argument to this SIN function in Excel, it will not recognize it as a valid argument. As a result, Excel will display an error messag...

How do you find the amplitude and period of a sine function? For a sine function of the form A sin(Bx), the leading coefficient A will change the amplitude of the function. If A < 1, then the amplitude is decreased, and if A > 1, then the amplitude is increased. If A is negati...
sin(A + B) = sinAcosB+ sinBcosAcos(A + B) = cosAcosB- sinAsinBWe know that tan(x) =and that the same relationship is true for the doubleangle/ additional formula.[ mark ]Thus, we can write[1 mark]If we divide each term by we get the followingCancelling out the left- ...
