Question 4 < Rewrite cos(x) in terms of sin(x)… bartleby

Web5 apr. 2024 · 1 Answer Eddie Apr 5, 2024 tan(cos−1( − x 5)) = ± √25 −x2 x Explanation: You want: tan(cos−1( − x 5)) = tanα Well: α = cos−1( − x 5) ⇒ cosα = − x 5 So in the first instance, this is: tanα = √25 − x2 −x The other possibility is: tanα = −√25 −x2 −x = √25 −x2 x So: tan(cos−1( − x 5)) = ± √25 −x2 x Answer link WebYou're just compressing the cosine wave. So there's not a nice and neat formulation for how the results compare, as you can see from the cos(2x) formulation, which is already sort … chisholm financial planning

To see how this behaves as x gets large, recall the graphs of the two exponential functions. y x ex 2 2 e−x As x gets larger, ex increases quickly, but e−x decreases quickly. So the second part of the sum ex/2 +e−x/2 gets very small as x gets ... graphite transfer paper hobby lobby
