**How do you evaluate arcsin(-1) without a calculator**

So work out the connections on the unit circle and apply the results to your particular scenario. Try it out: plug in an angle and see what percent of the height and width it reaches: The growth pattern of sine …... There is no phase of a sine wave. A sine wave has no phase. A phase can only develop between two sine waves. Two sine waves are mutually shifted in phase, if the time points of its zero passages do not coincide. The word phase has a clear definition for two pure traveling AC sinusoidal waves, but not for music signals. All equalizers shift phase with frequency. Without any fixed-point no

I know cos60= 1/2 but don't get how to get cos120 in exact form without a calculator It is not difficult. If we leave the sign for the moment, the following angles have the same value. 60, 120, 240, 300. how to take care of mint plant indoors Unless you learn to recognize the ways your calculator represents numbers and combines these representations, you might find yourself misinterpreting correct calculations without even realizing it. The purpose of this section is to give you a few simple ways of making sure you have the basics down on how your calculator works, and a few simple ways you can test how someone else's works, in

24/01/2005 · If you didn't notice, the thread is about Ice wanting to know about counting the area of a circle without a calculator; therefore, you need to approximate quite a bit. If he can't multiply numbers just because they're on the wrong side of a decimal place I'd have concerns about what his maths teacher is doing all day. how to stop being taken advantage of at work Find sin 150 You may find sin 150 by 2 ways: First way. Trig Table gives --> sin 150 deg, or sin ((5pi)/6), = 1/2 Second way: by the trig unit circle. sin ((5pi)/6) = sin (pi/6) = 1/2 . SOCRATIC Subjects .

- The trigonometric functions ‘sine Using a calculator, you can work out that R = [SHIFT sin0.429] = 25.4 . Therefore angle R = 25.4°to 1dp. 5. The cosine rule Similarly to the sine rule, you may be required to use the cosine rule during your GCSE maths exam in order to find the length of a side or size of an angle: The cosine rule is: \[{a^2} = {b^2} + {c^2} - 2bc\cos A\] However
