Determine the sine of the product of -10.4 times -78.2 enter plus for positive or minus for negative.
The product of -10.4 times -78.2 is positive. Therefore, the sine of this product is +1.
To determine the sine of the product of -10.4 times -78.2, we first need to calculate the product.
-10.4 times -78.2 equals 813.68 (rounded to two decimal places).
Since the product is positive (813.68 is greater than 0), the sine of the product is positive. Therefore, the answer is "plus".
To determine the sine of the product of -10.4 and -78.2, we need to follow these steps:
1. Multiply -10.4 by -78.2: (-10.4) × (-78.2) = 812.08
2. The result of the multiplication, 812.08, is positive, as multiplying two negative numbers yields a positive number.
3. Since the sine function deals with angles in a unit circle, we need to convert the number 812.08 into an angle. However, the sine function itself does not output positive or negative; it only provides a ratio between -1 and 1.
If you are looking for the sine of an angle measured in degrees or radians, you would calculate the sine of 812.08. However, if you want to know whether the sine value is positive or negative, you need to consider the quadrant in which the angle lies.
If the 812.08 angle is measured in degrees, divide it by 360 to find its equivalent angle within a full circle. Remainder of the division (812.08 % 360) will determine the angle within the range of 0 to 360 degrees.
Finally, you can compare the angle within the appropriate quadrant (0 to 90 degrees, 90 to 180 degrees, 180 to 270 degrees, or 270 to 360 degrees) to determine whether the sine value would be positive or negative, according to the positive/negative ratios in each quadrant.
