Suggestions and corrections for my trigonometry chart?

[rain lark]

I am studying trigonometry and I was making a chart to understand the relations between the terms, values and elements better.
Can anyone check if it seems right and maybe even suggest improvements?

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Also yes I made it in paint, if anyone knows a better digital alternative I'm all ears.

No clue what it's suppose to encode

[rain lark]

how you go from what to what

[slender fractal]

Yes

[rain lark]

Angle tan gets you tan angle which is O / A

no?

[slender fractal]

If you're in a right triangles yes

SOHCAHTOA

[rain lark]

oh oops I forgot to mention that

[slender fractal]

Also if your =HYPOTENUSE is supposed to be pythagorean... it's wrong

[rain lark]

why?

[slender fractal]

Reread the theorem...

It's a^2+b^2=c^2

[rain lark]

oh wait its hypotenuse squared right?

[slender fractal]

For legs a and b, and hypotenuse c

[rain lark]

I added a superscript 2 to the hypotenose

this is what you meant?

[slender fractal]

sure

still confused on why you have something about gradient, and why you want so much redudancy

especially when... there's no 100 to be seen in the gradient formula

[rain lark]

I think its gradient percentage

I just recall having to multiply tan angle by 100 to get gradient in class

I study mathematics in dutch so it can be a mistranslation

[slender fractal]

yeah... no

gradient is rise/run, which is just tan(t) for whatever angle t

there's no 100

but either way, it just feels overly complicated when the typical mnemonic SOHCAHTOA encapsulates all that and more

[rain lark]

when you say sohcahtoa

I cannot make any sense of that

[slender fractal]

Sine: Opposite Hypotenuse
Cosine: Adjacent Hypotenuse
Tangent: Opposite Adjacent

SOHCAHTOA

[rain lark]

yeah this graph is way more easy for me to memorize it

if it was complete

[slender fractal]

Ok... have fun making 5 more then?

[rain lark]

I will find a way

That isnt even the original graph btw, the original is in dutch and its also colour coded but its in my notebook which I don't have with me rn and taking pictures looks horrible
