Yes, this is correct. My earlier response, which is now deleted, was incorrect. Sorry to have misled you.Math10 said:sin(-3*pi/2)=1, am I right?
A limit in calculus is the value that a function approaches as the input (x) approaches a certain value.
To find the limit of a function at a specific point, you can plug in the given point into the function and solve. However, if the function is undefined at that point, you will need to use other methods such as factoring, rationalizing, or using L'Hopital's rule.
The purpose of finding the limit of a function is to understand the behavior of the function at a specific point. This can help determine if the function is continuous, has a removable/discontinuity, or has infinite or oscillating behavior at that point.
To solve for the limit of a trigonometric function, you can use the properties of trigonometric functions to simplify the function. If the function is still indeterminate, you can use trigonometric identities or the squeeze theorem to evaluate the limit.
The limit of sin((pi*x*y)/4) at (x,y)--->(-1, 6) is -1. This can be found by plugging in the given point into the function and solving, or by using the properties of sine and evaluating the limit using the squeeze theorem.
