Can anyone tell me how should I convert ratios to trigonometric angles
Dhruv00:
you are asking if you have given a trigonometric ratio then for which angle does it stand?
Yes
please tell
for example angle for cot3/4
Please answer
is it cot 3/4 or cot^-1 3/4

This is simple.
------------------------
Let you have given a ratio of perpendicular to the hypotenuse which is know as sine.
-----------------------
sin @= 1/2 (say)
to find the value of angle you have to convert this trigonometric function in to inverse trigonometric function.
For this shift sin to right hand side
=> @ = sin(inverse) 1/2
=> @ = 30°
-----------------
In order to calculate any angle just shift the trigonometric function to its right hand side.
After shifting it will become inverse trigonometric(circular) function.

what to do after this?
since cot (inverse) 3/5 is not a well known value ,u have to take the help of table
Table me in bas 90 degrees tak hote hain
there is no value like 3/5 in table
My teacher will scold me if I will go empty mind
there is
Ha ha ha is that so
I must say -
thou who spoke these words should be banished from whence thee came
Oh I thought you said that there is empty place in my head. I had not read those previous comments you were giving answers . Right!!
