Answer:
"General Formulas" in mathematics is the general equation you can use for certain things, by just adding the numbers given to the equation so that you can solve the problem.
Form example:
The general formula to find the y-intercept: y=mx+b
Hope this helped!

Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).
It is given that tanα=3.
Sinα(Sinα) = [], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α = .
Cos4α =
No because there will be a remainder i think
