How get values from a graph or prediction

Question

hi, i know thet find a value of prediction like model.predict[1.4] "lets assume result is 5". this gives me prediction of my model. My question is how get x values which gives me 5 ? İn other words i want to know in which points my prediction is 5?

İt should be smthg like that
Model.prepredict[5] which gives me 1.4

Same like let's assume i have graph like
a=sin(np.arange(0,10,0.1)

How can i find, Which values makes a equal 0.5 ?
İn this condition result should be(pi/6, 5pi/6 ......)

Thank you

Answer 1

You didn't understand the question. Because models don't have any formula. İf they have u can tell me how can I extract the formula from model. For example
mymodel = np.poly1d(np.polyfit(X, Y, 12))

How can I extract this my model formula and who can solve this 12th degree polynomial function in elementary school:)

Answer 2

İt is really funny that you still think a model formula is changed easily by subject. This is not solution. There must be much more easy way. İ doubth about ur knowledge about this situation because it is not elemantary math. Whatever thanks for not helping me:)

İ gave you -1 because it won't help me. And i don't know it effects ur profile. Sorry, if so i will gave +1 for ur help.
