Here, we want to get the values of the six trigonometric functions
Firstly, we need the measure of the third side of the triangle
Let us call this third side x
Mathematically, the square of the hypotenuse ( 4 root 2) is equal the sum of the two other sides
The above is the Pythagoras' theorem
Thus, we have it that;
![\begin{gathered} (4\sqrt[]{2})^2=4^2+x^2 \\ 32=16+x^2 \\ x^2=\text{ 32-16} \\ x^2\text{ = 16} \\ x\text{ = 4} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/4oltb759ny16avs1lkntmr0a7tuf75tlzv.png)
Thus, we have the opposite and the hypotenuse as 4
We start calculating the functions as follows;
a) Sine
This is the ratio of the opposite to the hypotenuse.
![\sin \text{ }\theta\text{ = }\frac{4}{4\sqrt[]{2}}\text{ = }\frac{\sqrt[]{2}}{2}](https://img.qammunity.org/2023/formulas/mathematics/college/ipwnzicv26zi3nzgm89qzodndbcyzxhvvs.png)
b) Cosine
This is the ratio of the adjacent to the hypotenuse
Since the adjacent value id equal to the opposite, we have the sine and cosine equal
![\text{cos }\theta\text{ = }\frac{4}{4\sqrt[]{2}\text{ }}\text{ = }\frac{\sqrt[]{2}}{2}](https://img.qammunity.org/2023/formulas/mathematics/college/8dk4hdamq60ef26tw3vw3fhuof0fr1rolb.png)
c) Tangent
This is the ratio of the opposite to the adjacent
We have this as;

d) Secant
This is the reciprocal of the cosine
Mathematicaly, it is the ratio of the hypotenuse to the adjacent
We have this as;
![\sec \text{ }\theta\text{ = }\frac{4\sqrt[]{2}}{4}\text{ = }\sqrt[]{2}](https://img.qammunity.org/2023/formulas/mathematics/college/7hjvk1dtmo0m9a5dnos878nm0tz6dpo4rt.png)
e) Cosecant
This is the ratio of the hypotenuse to the opposite
Mathematically, we have this as;
![co\sec \text{ }\theta\text{ = }\frac{4\sqrt[]{2}}{4}\text{ = }\sqrt[]{2}](https://img.qammunity.org/2023/formulas/mathematics/college/wd22xi687ay5yot91yrdt92ttwcn58r8bs.png)
f) Cot
This is the reciprocal of tan
It is the ratio of adjacent to the opposite
We have this as;
