Solution :<\/h2>\n

The value of cos 90 degrees<\/strong> is 0<\/strong>.<\/p>\n

Proof :<\/strong><\/p>\n

\\(\\angle\\) A of \\(\\Delta\\) ABC is made large and large until it becomes 90 degrees. As \\(\\angle\\) A gets large and large \\(\\angle\\) C gets smaller and smaller. Side AB goes on decreasing. The point A gets closer to point B. When \\(\\angle\\) C becomes very close to 0 degree. The side AC almost coincide with side BC and side AB becomes to zero.<\/p>\n

So, AC = BC and AB = 0<\/p>\n

\"90<\/p>\n

By using trigonometric formulas<\/a>,<\/p>\n

\\(cos 90^{\\circ}\\) = \\(base\\over hypotenuse\\) = \\(b\\over h\\)<\/p>\n

\\(cos 90^{\\circ}\\) = \\(AB\\over AC\\) = \\(0\\over AC\\) = 0<\/p>\n

Hence, the value of \\(cos 90^{\\circ}\\) = 0.<\/p>\n","protected":false},"excerpt":{"rendered":"
