This is equal to 19 over 20. How to Get 2 Decimal Places in Python - Javatpoint. So in the LHS we take the cosine of theta, and then take the inverse cosine, which is just theta, so we have. Cimal(decimal) provides a 50-digit decimal point by default. You will not be expected to do this until an advanced course in calculus.

So let x = cos(theta). Why is he still multiplying cos-1 to the rest of the problem when he should be dividing it? The ceil() method is used in the program below to return the rounded-off value of the supplied floating-point value up to two decimals. I don't it says to two decimal places. In Sal's previous video, he said the formula was a^2=b^2+c^2-2ab cos Theta. Other than that, either you will be allowed to use a calculator or you'll be given the values. You know that from this point to this point along the base, straight along level ground, is 60 meters. Well you know three sides of a triangle and then we want to figure out an angle. So I'm just gonna subtract 6, 100 from both sides so that I get closer to isolating the theta.

Three goes into 57, is that 19 times? So to solve, you subtract and divide. Created by Sal Khan. By clicking Sign up you accept Numerade's Terms of Service and Privacy Policy. So it's 2, 000 plus 3, 000, plus 5, 000. Using ceil() Function. 12 Free tickets every month. If they give you 1 angle and 2 sides and the given angle is opposite of one of the sides and the unknown angle is opposite of the other given side, then you can use law of sines.
