14. sin³ 2xcos4x=.... A. (2 cos4x+cos8x-1) B. (2 cos4x-cos8x+1) 4 C. (2 cos4x+cos8x+1) D. — (2 cos4x-cos8x+1) E. (2cos4x+cos8x+1) 2
Answer (4)
cell:a group of micro oraganisms known as cell cell is the basic unit of life tissue:a group of cells known as tissue organ;a group of tissue known as organ organ system:organism r of 2types they r multicellular and unicellular multi means number of and uni means single example for multi cellular organism cockroach;lizard etc and unicellular is amoeba,paramoecium etc...... they r depeded on each other
Cell ; Cell is a basic structural and functional unit of all living organisms. Tissues ; tissue is a group of cells that performs a specific function. Organ ; Organ is a group of tissues that performs a specific function. Organ system ; An organ system is a group of organs that work together to perform one or more functions. Organism ; An individual form of life that is capable of growing, metabolizing nutrients and reproduction is called an organism.
Cells are the basic units of life that group together to form tissues. Tissues combine to create organs, which work together in organ systems. An organism is a complete, individual living entity made up of these systems.

Jawaban:soalsin³ 2xcos4x=caranya1. Ubah sin³ 2x: sin³ 2x = sin 2x . sin² 2x2. Ubah sin² 2x: Ingat identitas trigonometri cos 2θ = 1 - 2sin² θ. Maka, sin² θ = (1 - cos 2θ)/2. Jadi: sin² 2x = (1 - cos 4x) / 23. Substitusi: sin³ 2x = sin 2x . (1 - cos 4x) / 24. Kalikan dengan cos 4x: sin³ 2x cos 4x = sin 2x . (1 - cos 4x) / 2 . cos 4x = (sin 2x cos 4x - sin 2x cos² 4x) / 25. Ubah sin 2x cos 4x: Ingat rumus perkalian sinus dan cosinus: sin A cos B = ½ [sin(A+B) + sin(A-B)]. Maka: sin 2x cos 4x = ½ [sin 6x + sin (-2x)] = ½ [sin 6x - sin 2x]6. Ubah cos² 4x: Ingat identitas trigonometri cos 2θ = 2cos² θ - 1. Maka, cos² θ = (1 + cos 2θ)/2. Jadi: cos² 4x = (1 + cos 8x) / 27. Substitusi kembali: sin³ 2x cos 4x = (½ [sin 6x - sin 2x] - sin 2x . (1 + cos 8x) / 2) / 2 = (sin 6x - sin 2x - sin 2x - sin 2x cos 8x) / 4 = (sin 6x - 2sin 2x - sin 2x cos 8x) / 4 Kesimpulan:Tidak ada jawaban yang sesuai dengan pilihan yang diberikan dengan caranya.
