Use the sine ratio to find the height of the kite: sine = opposite (height of kite with the horizontal) divided by the hypotenuse (the string) Rearrange the formula: sine*hypotenuse = opposite sine 25 degrees*150 = 63.39273926 feet Height of kite above the ground: 63.39273926+4.5 = 67.89273926 feet Therefore the kite is 68 feet above the ground to the nearest foot
sine 810 = sine 90 = 1
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
Sine 3.3 degrees is about 0.057564. Sine 3.3 radians is about -0.157746. Sine 3.3 grads is about 0.051813.
sine 45 = 0.850903525
When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive

Sine does not converge but oscillates. As a result sine does not tend to a limit as its argument tends to infinity. So sine(infinity) is not defined.
The sine of 0 is 0.

for modified sine wave inverter (most common type, if it doesn't say than it's modified sine) a safe bet would be the 1,000 watt inverters or higher because the mini fridge will surge 3-5 times its continuous rated wattage for anywhere from 1-10 seconds. so although your fridge only needs 90-150 watts to run it might burn out an inverter say in the 150-300 watt range. a modified sine wave 1,000 watt inverter is about $65-100. you are supposed to buy pure sine wave inverters for a fridge, but those are expensive. you do run the risk of ruining the fridge faster if you do not run pure sine wave , however.
