My calculator is defekt, and I need to finish an assignment in trigonometry.
Does anyone know any good online calculator to use sin,cos and tan ?
Im currently using this one : eCalc - Online Scientific Calculator
seems like a good calculator, but I dont get the following:
I am looking at a sample:
Let x represent the hypotenuse, side AC.
sin = O/H
Dividing 32 by sin 56 using the above calculator gives me a totally different solution. How will I get the correkt answer using that calculator ?
38.6 is the correct answer for the euqtion you've posted. If the on-line calculator is NOT giving you this answer, can I hazard a guess and say it's giving you a negative answer ....? (This would happen if the calculator thought the angle was being measured in radians rather than degrees).
If it works like the Google calculator ( sin(30 degrees) - Google Search ) then you have to type "56 degrees" as part of the input.
Somehow I have to use the 2nd function like in a scientific calculator; but the calculator I have given has no 2nd function and like you recognized it measures in radians ... i tried to put degrees beside it, but it didnt work... using the google calculator I get the sin number; but somehow I have to enter that number using the 2nd function in a regular scientific calculator to get my final answer ... do you know what to write to get that in google ?
