MHB Find All Trig Functions of Gamma Given cot(gamma)=4/3

AI Thread Summary
Given cot(gamma) = 4/3, the triangle formed has sides AC = 4, BC = 3, and AB = 5, which is derived using the Pythagorean theorem. From this, the sine, cosine, and tangent functions can be calculated: sin(gamma) = 3/5, cos(gamma) = 4/5, and tan(gamma) = 3/4. Additionally, the cosecant, secant, and cotangent functions are found to be csc(gamma) = 5/3, sec(gamma) = 5/4, and cot(gamma) = 4/3, confirming the initial condition. All five remaining trigonometric functions of gamma have been successfully determined. This solution illustrates the relationship between the cotangent and the other trigonometric functions.

Given cot(gamma)=4/3 find all possible values of the five remaining trigonometric functions of γ.

Could somebody help me here?
Thanks

Let's make a diagram.

\begin{tikzpicture}
\draw (0,0) node[anchor=north]{$A$}
-- (4,0) node[anchor=north]{$C$}
-- (4,4) node[anchor=south]{$B$}
-- cycle;
\end{tikzpicture}

Using the given information and Pythagoras:

$$\overline{AC}=4\quad\overline{BC}=3\quad\overline{AB}=5$$

Now, can you determine the five remaining trigonometric ratios?
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
