There are a few ways. First, there are a multitude of trigonometric tables which list the sines and cosines of a variety of values. if you now one trigonometric value of a number, you can find all the others by hand, and you can also use a Taylor series approximation to find a fairly accurate value. (In fact, many calculators use Taylor series to find trigonometric values.)

How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
How do you find the inverse tangent without a calculator?
You cannot.
How do you find log6?
Nowadays you cannot do it without a calculator.
How do you find the length of a cube without a calculator?
Use a ruler
How do you know the angle without using a calculator?
To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
How do you find trigonometric ratios of angles greater than 90 degrees?
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
How can trigonometric ratios be used to find the area of a triangle?
By themselves, they cannot. Two similar triangles have the same angels and so they have the same trig ratios. You need to know the length of at least one side to determine the area.
Uses of six trigonometry functions?
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.
What is tan on a scientific calculator?
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
How do you find the inverse tangent without a calculator?
You cannot.
How do you find log6?

Is 302 divisible by 4?
Find a calculator or use your brain! And without a decimal, no.
What is 50x5?
250(how about use the calculator on your computer next time if you can't find it out? This is like baby stuff, easy without a calculator!)
How to get the equivalent ratios of 60:12?
The calculator will simplify the ratio A : B if possible. Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to create values for C and D. Compare Ratios and Solve for the Missing Value: Enter A, B and C to find D.
How do you know the angle without using a calculator?
To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
Where can one find a list of trigonometric identities?
Trigonometric identities involve certain functions of one or more angles. These identities are useful whenever expressions involving trigonometric functions need to be simplified.
