Are you somali bro 🤔

Hello i really don't get the correct answer in theta. The answer is always 0.63 something. What should I do?

[@Civiltimes2210]

Simplywrite in your calculator this: Shift+sin(0.63)....this means sin inverse

[@ryanmccullough4831]

by doing that it says sin^-1(.63)=.68 what am I doing wrong@@Civiltimes2210

[@patrick_noah]

​@@Civiltimes2210why did we look for the inverse??? You didn't state why in the video

[@nathangeco]

θ = arcsen( 0,6394) = 39,8

[@CBKCUSTOM]

wrong answer on sin theta

[@Civiltimes2210]

As long as the formulas are correct it does not matter sometimes if we get the wrong answer. However, for this particular example, I have checked it so many times before being uploaded and it is the correct answer.

I have a question, no matter how hard I try, the result does not come out 212.6. How do I do the math?

[@Civiltimes2210]

Furst Cos115=-0.42, and inside the square there is a ❝minus❞ sign, finally the negative sign changes to positive.

@@kimsoyoul9734 So, did you get the result as 212.6 now?

i get in sinelaw is 0.6394
