When can you use the inverse of sin?
You can use the inverse of sin when you want to solve an equation where x is the angle you're trying to find. Say sin(x)=32/50 Since you can't plug "x" into your calculator, use the arc sin (represented on your calculator by sin -1) on both sides to get rid of the sin. This is how it would plug into your calculator: sin-1 (32/50) Whatever the answer is would be what "x" equals.
How do you find cosine on a scientific calculator?
First make sure the calculator is in 'Degree Mode'. Then press 'Cos' , followed by the angle in degrees, say '60' degrees, then press equals (=), and the answer should read '0.5'. NB If the calculator is in 'Radiuan Mode' Press 'Cos' followed by ' pi' divide '3' . Then equals (=) , again the answer should be '0.5'.

How do you round 25.0096 to the nearest thousandth?
25.0096 rounded to the nearest thousandth would be25.01. Why? Well, first you have to find the thousandth place. In this case it is the 9. Then, you look to the right of your ROUNDING digit- this is 6. 6 is the KEY digit. Since 6 is HIGHER than 5, you know you have to round UP. Normally, you would simply change the roundig digit to the next digit up, but since he number after 9 is two digits, you have to make an exception. What you do is you change the 9 to a zero and carry the 1 to the hundredths place. Finally, drop all zeroes after the hundredths place.hope this helps!
