$\alpha \int_{0}^T \text{Sin}(fi−fk+Δf)∗t) \, dt$ — Why is it not giving wrong answer? [closed]
$$\alpha \int_{0}^T \text{Sin}(fi−fk+Δf)∗t) \, dt $$
I am integrating this in Mathematica,
My code is
(1/2)*α*Integrate[Sin[2*Pi*(fi - fk + δf)*t], {t, 0, T}] + Ν1
It should have been Cos(something) …

Does anyone here know how can we extract Lambda from the following equation
I am working on an estimation problem where I have the following
Code is
A = 1 + Pi*Csc[(1 + Pi)*\[Lambda]]^2*
(Pi + Sin[2*(1 + Pi)*\[Lambda]])
Can anyone help me how can we extract $\lambda$ fr …

Simple Question: How to simplify what is inside the Sin function like below?
I have this code of Mathematica
(1/(2 (fj - fk) π))
Cos[(fj - fk) π T + (fj - fk) π (T + δt)] Sin[(fj -
fk) π T - (fj - fk) π (T + δt)]
There are a few terms inside these Sin functions that …
