for maxima diff(i) w.r.t.time=0 so 3cosΔt-4sinΔt=0
which gives tanΔt=3/4 now we can put it back into the original equation to find the answer to my question which is what i did
where tan alpha = 3/4
This uses the compound angle formula http://www.mathsrevision.net/advanced-l … e-formulae

which do you think applies?
]]>Just a question. This delta function, is a Dirac delta function, an impulse function or just a straight difference operator?
