**Solve the equation sin x cos x=0. eNotes**

sin(0°) Proofs 30° 45° and 60° Here are two simple triangles which give us the formulae for the trig values of these three angles:- This triangle is just a square cut along a diagonal. If the sides are of length 1, the diagonal is length v2. This gives the sin, cos and tan of 45°. Here is an equilateral triangle where all sides and all angles are equal (to 60°). If the sides are of... I could use simple sin & cos to work it out if it was moving on just the X or Z axis, but what if it's at 3,8 (x,z)? Maybe an average of the sin/cos heights?! Maybe an average of the sin/cos heights?!

0.5 = sin(30 °) Read: 'Zero point five is the sine of thirty degrees.' Or: sin(30 °) = 0.5 . Read: 'The sine of thirty degrees is zero point five.' Below is a listing of several popular input and output values for the three main trigonometry functions. You do not have to work at memorizing this table. After you use trigonometry for a while, these values will be remembered quite easily. 0... As we can see, the equation is linear, in sin x and cos x. The way of solving this kind of equation is to divide enire equation with "cos x".

**How can you find the sine of 90 degrees without a calculator?**

`2\ sin t ? 1.732\ cos t =` ` 2.646\ sin(t ? 0.714)` So the maximum value of this is `2.646\ "A"`. To find when this occurs, we need to solve: `2.646\ sin(t ? 0.714) = 2.646` i.e. `sin(t ? 0.714) = 1` `t ? 0.714 = ?/2` `t = 2.29` So `t = 2.29\ "s"` is the time when the maximum is first reached. The Cosine Form . We can also express our sum of a sine term and a cosine term using...

**How can you find the sine of 90 degrees without a calculator?**

7/02/2010 · Always convert the percentage to a decimal by dividing by 100. 2% is then 2/100 = 0.02. Then multiply this by the number you are trying to find the percentage of.... The fixed point iteration x n+1 = sin(x n) with initial value x 0 = 2 converges to 0. Zero is the only real fixed point of the sine function; in other words the only intersection of the sine function and the identity function is sin(0) = 0.

## How To Work Out Sin 0

### sin x > cos x on the interval 0 x < 2. From the unit circle we see that sin x and cos x can only have the same value in two places, in x = /4 and x = 5 /4 (45 ° and 225 °). The equation sin x = cos x can also be solved by dividing through by cos x .

- The angle associated with sin 0.923 or cos 0.384 is 67.38 degrees. Add 90 to the angle you just calculated, and subtract the sum from 180. This will give you the third angle.
