sin(0) = 0, sin(90) = 1, sin(180) = 0, sin (270) = -1 cos(0) = 1, cos(90) = 0, cos(180) = -1, cos (270) = 0 tan(0) = 0, tan (180) = 0. cosec(90) = 1, cosec(270) = -1 sec(0) = 1, sec(180) = -1 cot(90)= 0, cot(270) = 0 The rest of them: tan(90), tan (270) cosec(0), cosec(180) sec(90), sec(270) cot(0), cot(180) are not defined since they entail division by zero.
216/360 times 2pi which simplifies to 6pi/5. Rough figure 6 x 3.14/5 = 18.84/5 or 3.8 to the nearest tenth.
The sin of 30 is sqr(3)/2 so 6 * sqr(30) is 6 * sqr(3)/2 this is also 6/2 * sqr(3) which simplifies to 3 * sqr(3) which is approximately 5.19615242
A roof angle of 6 degrees = 1.26 / 12 rise or pitch.
You need to know the trigonometric formulae for sin and cos of compound angles. sin(x+y) = sin(x)*cos(y)+cos(x)*sin(y) and cos(x+y) = cos(x)*cos(y) - sin(x)*sin(y) Using these, y = x implies that sin(2x) = sin(x+x) = 2*sin(x)cos(x) and cos(2x) = cos(x+x) = cos^2(x) - sin^2(x) Next, the triple angle formulae are: sin(3x) = sin(2x + x) = 3*sin(x) - 4*sin^3(x) and cos(3x) = 4*cos^3(x) - 3*cos(x) Then the left hand side = 2*[3*sin(x) - 4*sin^3(x)]/sin(x) + 2*[4*cos^3(x) - 3*cos(x)]/cos(x) = 6 - 8*sin^2(x) + 8cos^2(x) - 6 = 8*[cos^2(x) - sin^2(x)] = 8*cos(2x) = right hand side.

To round 12.456 to the nearest hundredth, we look at the digit in the thousandth place, which is 6. Since 6 is equal to or greater than 5, we round up the digit in the hundredth place, which is 5. Therefore, 12.456 rounded to the nearest hundredth is 12.46.

6/11 rounded to the nearest hundredths place is 0.55
58.056The nearest hundred falls between the 5 (the hundredth) and the 6 (the thousendth). Since the thousendth is a 6, it's rounded upwards =58.06
When rounding to the nearest hundredth, you look at the thousandth place. In this case, the digit in the thousandth place is 6. Since 6 is equal to or greater than 5, the digit in the hundredth place (7) is rounded up by 1. Therefore, 0.676 rounded to the nearest hundredth is 0.68.
To round 0.36 to the nearest hundredth, we look at the digit in the thousandths place, which is 6. Since 6 is greater than or equal to 5, we round up the hundredths place. Therefore, 0.36 rounded to the nearest hundredth is 0.37.
