(1 Point)
sin (0) = -2/2 270º < 0 < 360° how to solve
Answer:
[tex]\cos(2\theta) = 0[/tex]
Explanation:
Given
[tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex]270^o < \theta < 360^o[/tex]
Required
[tex]\cos(2\theta)[/tex]
Recall that:
[tex]\sin^2(\theta) + \cos^2(\theta) =1[/tex]
Substitute: [tex]\sin(\theta) = -\frac{\sqrt 2}{2}[/tex]
[tex](-\frac{\sqrt 2}{2})^2 + \cos^2(\theta) =1[/tex]
[tex]\frac{1}{2} + \cos^2(\theta) =1[/tex]
Collect like terms
[tex]\cos^2(\theta) =1-\frac{1}{2}[/tex]
[tex]\cos^2(\theta) =\frac{1}{2}[/tex]
[tex]\cos(2\theta)[/tex] is calculated as:
[tex]\cos(2\theta) = \cos^2(\theta) - \sin^2(\theta)[/tex]
So, we have:
[tex]\cos(2\theta) = \frac{1}{2} - (-\frac{\sqrt 2}{2})^2[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{2}{4}[/tex]
[tex]\cos(2\theta) = \frac{1}{2} - \frac{1}{2}[/tex]
[tex]\cos(2\theta) = 0[/tex]

Gandhi was a non-violent Indian independence leader. The correct option is a.
Who is Mahatma Gandhi?Mahatma Gandhi, was an Indian revolutionary, anti-colonial nationalist, and political ethicist who employed nonviolent resistance to lead the successful campaign for India's independence from British rule and later inspire movements for civil rights and freedom across the world.
The honorific epithet Mahatma, first applied to him in 1914 in South Africa, is now used throughout the world. Born and raised in a Hindu family in coastal Gujarat, Gandhi trained in the law at the Inner Temple, London, and was called to the bar at age 22 in June 1891. After two uncertain years in India, where he was unable to start a successful law practice, he moved to South Africa in 1893 to represent an Indian merchant in a lawsuit. He went on to live in South Africa for 21 years.
Gandhi adopted the short dhoti woven with hand-spun yarn as a mark of identification with India's rural poor.
