programming my language
hello,
I wanted to know about new updates and new features of programming
Hi Asghar,
sin2u = sin3u is only true if u = 0.
So then put u = 0 into the second expression
sin(0 + 30) = sin30 = 1/2
Let me know if you have any further questions!
Thank you do much lewis .but dont you think of any other way.
i mean is this the only possible way.
Yes, that is the only possible solution.
In order for sin2u = sin3u to be true, 2u = 3u must be true. This is only true if u = 0.
I'm at algebra 1 functions level, Geometry circle highschool level, and I haven`t even started trigonometry yet, I'm thinking to stick to the geometry section finishing the https://www.khanacademy.org/math/geometry-home/cc-geometry-circles then the trigonometry then going back to algebra, I'm not going to do trigonometry in algebra and pre-calc not section not until I'm finished the geometry all content high school level and trigonometry and yet I don`t want to bore myself into putting myself of KA.
I disagree. There are infinitely more answers. For example, if you use u=(pi) , the equation also works, where both sides equal 0. All possible angles for u can be represented as the following, where k is an integer.:
Radians -
u = 2πk
u= (π/5) + (2πk/5)
Degrees -
u = 360°k
u= 36° + 72°k
Another example is u=π/5 , where both sides would equal approximately 0.951
What trigometry section is that sum from.
I don't think all the steps I used can be found on Khan Academy
