Cos theta looks a bit complicated but can be broken down into two components which are adjacent sides divided by the length of hypotenuse or A over H where A represents Adjacent Side and H stands for Hypotenuse. 6. I'm struggling to understand Cos theta. Can someone explain it more simply...

好, 那现在我们已经得到了一个等式, 即 \[z\left( \theta \right)=\cos \theta +\text{i}\sin \theta \], 其中 \[z\left( \theta \right)\] 的意思是说这个点或者说复数 z 的位置取决于角度 \[\theta .\] 那么问题就来了, 如何得到 \[z\left( \theta \right)={{\text{e}}^{\text{...
I = Vpk * cos(theta(t)) = 0.03 * cos(theta(t)) Vpk = 0.03 V Vrms = Vpk / sqrt(2) = 0.03 / sqrt(2) = 0.021213 V Power = Vrms2 / Zohms = (0.021213)2 / 50 = 9 uW PowerdBm = 10 * log(Power) + 30 = 10 * log(9u) +30 = -20.45 dBm or PowerdBm = 20 * log...
Explanation: The IMARGUMENT function returns the angle (also known as the argument, or theta) of the given complex number in radians. This is the angle θ such that, for any complex number in Cartesian form x + yi, x + yi = reiθ where r is the magnitude of the number.IMCONJUGATE...

Taking the cosine of an angle gives the ratio of theadjacentside divided by thehypotenuse. Side "b" is adjacent to the angle, and the hypotenuse is still side "c", the cosine of theta will be equal to b/c. cos(θ)=adjacenthypotenuse=b/c ...
These identities are useful for converting between trigonometric functions: csc(theta) = 1/sin(theta) sec(theta) = 1/cos(theta) cot(theta) = 1/tan(theta) Quotient Identities: Quotient identities relate the trigonometric ratios of one angle to the ratios of other trigonometric functions. These ...

The dot product of two vectors is the sum of the multiplication of each component, giving a scalar result for the 'multiplication' of two vectors. There are two main formulas, depending on your form of vectors. ||\vec{v}|| is the length/magnitude of the vector and \Theta is the angle...
