tan u/2 = sin u/1+cos u
The exact value of sec 4pi divided by 3 is 1/3.
cos(195) = -0.965925826289
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
cos20 x cos40 x cos80 = 0.0300 radians = 0.125 degrees (the value for radians is given to four decimal places, the value in degrees is exact)
It's c2=a2+b2 where c is the hypotenuse (longest side), a and b are the other sides, it helps find if it's a right-angle triangle.
It depends on what x is - an angle, a side, a diagonal, etc
Cosine(30) = sqrt(3)/2
For trigonometry if you have the value of the hypotenuse and the angle, it depends what side you are trying to find. If you are looking for the side across from the angle, the formula is sine(angle)=opposite side divided by hypotenuse. If you are looking for the side adjacent to the angle, the formula is cosine(angle)=adjacent side divided by hypotenuse. Hope this helps!
To find the exact value you could:use exact values rather than estimates - as inputs;use exact formula instead of approximations,use calculus.There are other methods as well and the choice depends on the circumstances. Then, if Y is your value and E is the exact value,percentage error = 100*(Y - E)/E or 100*(Y/E - 1).
180 - interior angle = exterior angle
tapper angle formula of shaft
To find acceleration with mass and angle, you can use the formula: acceleration (force sin(angle)) / mass. This formula takes into account the force acting on an object at an angle and divides it by the mass of the object to determine its acceleration.
Exterior Angle = 360/number of sides. Interior Angle = 180 - Exterior Angle. Combining Interior Angle = 180 - (360/number of sides).
that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.
By using Pythagoras' theorem for a right angle triangle.
It is called Pythagoras' theorem because it's impossible to find the exact length of the hypotenuse of a right angle isosceles triangle which is an irrational number in the same way that it is impossible to find the exact area of a circle because the value of pi is also an irrational number.
There is no general formula. You need to measure it or else have a lot more information.
