what is sin regression?
You have much more success looking for sine regression
y= a * sine(bx+c) + d
You will find it here, but I suspect you need to be looking in your TI83 calulator book.

I'm not familiar with the term "sin regression." However, I can explain how to perform regression analysis and how to calculate the sine function if that's what you intended to ask.
Regression analysis is a statistical technique used to understand the relationship between a dependent variable and one or more independent variables. It helps to predict or estimate the value of the dependent variable based on the values of the independent variables.
There are different types of regression analysis, such as linear regression, polynomial regression, logistic regression, etc. These methods involve fitting a mathematical equation to the data points to find the best fit line or curve.
On the other hand, the sine function is a mathematical function commonly used in trigonometry. It relates the angle of a triangle with the ratio of the length of the side opposite the angle to the length of the hypotenuse. The sine function, denoted as sin(x), takes an angle (in radians or degrees) as an input and returns the corresponding sine value.
To calculate the sine value, you can use mathematical software or programming languages that support trigonometric functions. For example, you can use the sin() function in Python's math module or the SIN() function in spreadsheet software like Excel.
If you have any specific context or clarification about "sin regression," please let me know, and I'll be happy to help further.
