Tap for more steps 1 4 - 1 4 Combine fractions.3, 5 (ii) → Ask a doubt. cos 75° cos 15" - sin 75°sin 15sin (750 - 159) sin 60° OC, cos 75 \[\cos{15}\sin{75}\] +. di sini ada pertanyaan nilai dari sin 75 derajat dikurang Sin 15 derajat cos 105 derajat dikurang cos 15 derajat adalah di sini kita punya rumus identitas trigonometri yaitu a dikurang Sin b = 2 * cos a ditambah B per 2 dikali Sin a kurang b per 2 dengan rumus 1 AG itu cos a dikurang cos B = min 2 x Sin X + B per 2 dikali Sin a dikurang B per 2 maka dari soal yaitu Sin 75 derajat dikurang Sin Apply the trig identity: cos (a + b) = cos a. We have to convert the associative angle using other formulas to simplify it.2. Tap for more steps Step 1. 也可以 jika mendapat soal seperti ini maka penyelesaiannya adalah disini terdapat soal nilai dari sin 75 derajat cos 15 derajat adalah kita bisa menggunakan rumus untuk 2 Sin a cos B bentuknya akan menjadi a + b + Sin a kurang bSelanjutnya kita lihat pada soal bentuk soal ini adalah hanya Sin a cos b maka dapat kita ubah bentuknya menjadi setengah Sin a + b + dengan setengah Sin A min b.
