A colleague and I had to calculate a measurement for work today. One calculated it using Pythagoras' theorem, and another used the trigonometric function. We got different results, but I don't understand why.
12.04 was also correct due to the total length of the part.

Loading...Update: I only had to look in the book, it's been resolved 😅 I've already tried looking it up, but the examples never included vectors in the plane equation. I'm not expecting a complete solution, just an idea of ​​how to do it. Thanks in advance. To rephrase the question: How do I determine whether…
Can someone solve this problem for me? I would be grateful.
Hey, is this function (f(x)=x^3) strictly monotonically increasing, or just monotonically increasing?: Thank you.
Hello, I found the following problem online, which I find quite interesting. Can someone explain to me how to solve it?
Hello, can anyone help me with this word problem? There are a lot of numbers listed, but I don't understand what goes together. I only need the 3 terms that I have to set up to solve this problem. I hope someone can help me, thanks in advance!
If the angle is to be 54° and side a=9 and c=8, then this is the overall no rectangular Triangle and then the phrase of Pythagoras is known not true at all.
Ok the angles then do not vote the lengths (the upper ones were only thought out, would have had to think that the angles could not be so wrong). I’m a feathermaker and I was about drawing to calculate the leg length with height 9.04. Then this simply does not work with sinus cosinus because it does not give a correct triangle because of e.g. the round spring body and the material thickness which projects in the angle which would also have to be dressed but nevertheless thanks
I added the picture above
The 54° do not match the side lengths 8 and 9.
48.4° would be more correct because tan(48.4°) = 9/8.
with 54 and 9, these lengths are produced
