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
sin56=32/x
xsin56=32
x=32/sin56
x=38.6cm
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 ?
Sorry, are you saying your on-line calculator is NOT giving 38.6 ...?
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).
The on-line calculator is assuming that angles are measured in radians. You have to tell it that the angle is being measured in 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.
use this calculator
Scientific Calculator
input 56sin
then press 1/x
then multiply by 32 and you will get your answer
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 ?
I don't see the problem .....:
32/sin(56 degrees) - Google Search
Your first mistake is in not having an angle. Sin of what = 24/32.
So the equation should be sin(a) = 24/32 and solve for a.
arcsin(3/4) in degrees - Google Search
