Nilai dari cos 105° cos 15° sin 105° sin 15° mohon
therefore sin105+cos105= sin105 sin15 =2 cos (105+15)/2 sin(105–15)/2 =2 cos60 sin45 = 2 x 1/2 x sin45 =sin45 note this solution is without substituting values that one do your self after learning the formulae sin(A+B) etc20180731.
sin 15 cos 15 cos 75 sin 75 EXACT value with no calculator
sin 105° = sin 105∘ = sin (180° 75°) = sin (75°) = sin (90° 15°) = cos (15°) = cos (30°/2) = 1 + cos 30 ° 2 = 1 + 3 / 2 2 = − 2 + 3 4 = − 1 2 2 + 3 11K views View upvotes Answer requested.
15度，75度，105度，165度三角函数值分别是多少_百度知道
cos105°+cos15° = sin75°sin155° Stepbystep explanation LHS = cos105° +cos15° =cos(90°+15°)+cos(90°75°) /* We know that i ) cos(90°+A) = sinA ii) cos(90°A) = SinA = sin15°+sin75° =sin75°sin15° =RHS Therefore cos105°+cos15° = sin75°sin155° •••♪ Advertisement Still have questions?
