En bild för att förtydliga. Vid 45 grader (grön) är cos x = sin x och likaså 225 grader (grön). Och mellan 45 och 225 är det 180 grader. Därför är cos x = sin x vid alla gradtal som uppfyller 45 + n * 180 ( n ett pos/neg heltal) Vid 135 grader (röd) är c o s x = - sin x (och likaså vid 315 grader).

(7) sin x + sin y = 2 Recall derivative function ratio rule g(x)=f(x)/h(x) ⇒ g'(x)=[f '(x)*h(x)-f(x)*h'(x)]/h²(x) In our case f(x)=sinx ⇒ f '(x)=cosx h(x)=x² ⇒ h'(x)=2x hence Hi,. in CAS why not we get cos (x) ² + sin (x) ² = 1 and can we linearize the simplest forms of trigonometric forms as cos (2x) or sin (2x) Best regards,. sin x sin x + cos x cos x. = sin2 x + cos2 X = 25.

check-circle. Answer. Step by sin (x + y) = sinxcosy + cosxsiny sin (x − y) = sinxcosy − cosxsiny cos (x + y) = cosxcosy − sinxsiny cos (x − y) = cosxcosy + sinxsiny tan (x + y) = tan x+tan y.
