How to input sin 2
WebThe math.sin () method returns the sine of a number. Note: To find the sine of degrees, it must first be converted into radians with the math.radians () method (see example below). Web>>> import numpy as np >>> import math >>> x = 2 >>> np.sin (x) 0.9092974268256817 >>> (np.sin (x))**2 0.826821810431806 >>> (math.sin (x))**2 0.826821810431806 That worked with no problems. As bbye98 alluded to, it seems that maybe the problem is your variable 'x'. More posts you may like r/lisp Join • 2 yr. ago

WebAs many people have pointed out by now, sin 2 x is simply a "nickname" for ( sin x) 2. Therefore, sin 2 30 = ( sin 30) 2 = ( 1 / 2) 2 = 1 / 4. As it happens, though, there is another useful thing we can say about sin 2 x: sin 2 x = ( sin x) 2 = 1 2 ( 1 − cos ( 2 x)). We can see this using the double-angle formula for cosines: Web10 dec. 2024 · If you want to be understood, you will need to learn the language, even if you like your personal version better.

WebSecond, that kind of 2D array initialization is only standard in C. You would need to manually allocate the array on the heap using the C++ operator new [] (similar to the malloc function in C). However that's not idiomatic C++ and the whole point of the language is to avoid doing that which is why I won't explain how to do it.

You can factor it into (sin-1/2) (sin-1/2)=0, which means sin=1/2. So you know sin but you need cos. You can dig out your calculator, or use the rule that sin 2 + cos 2 = 1.
