Tentukan perbandingan trigonometri sinus, cosinus, tangen, cotangen, secan, cosecan, pada setiap segitiga berikut.

<p>Jawaban: &nbsp;sin C = 1/√2, cos C = 1/√2, tan C= 1/1 = 1, cotan C = 1, sec C = √2, csc C = √2, sin D = 1/√2, cos D = 1/√2, tan D = 1, cotan D = 1, sec D = √2, csc D = √2</p><p>&nbsp;</p><p>Ingat konsep berikut ini:</p><p>sin x = sisi depan x/sisi miring x</p><p>cos x = sisi samping x/ sisi miring x</p><p>tan x = sisi depan x/ sisi samping x</p><p>cotan x = 1/tan x</p><p>sec x = 1/cos x</p><p>csc x = 1/sin x</p><p>&nbsp;</p><p>sisi miring = √1²+1²</p><p>sisi miring = √1 + 1</p><p>sisi miring = √2<br>&nbsp;</p><p>sin C = 1/√2</p><p>cos C = 1/√2</p><p>tan C= 1/1 = 1</p><p>cotan C = 1</p><p>sec C = √2</p><p>csc C = √2</p><p>&nbsp;</p><p>sin D = 1/√2</p><p>cos D = 1/√2</p><p>tan D = 1</p><p>cotan D = 1</p><p>sec D = √2</p><p>csc D = √2</p><p>&nbsp;</p><p>Jadi, sin C = 1/√2, cos C = 1/√2, tan C= 1/1 = 1, cotan C = 1, sec C = √2, csc C = √2, sin D = 1/√2, cos D = 1/√2, tan D = 1, cotan D = 1, sec D = √2, csc D = √2</p>
