What is sin53 degrees
79863 with the calculator on the computer, select the angle of the scientific calculator, and first click sin to input the angle
What are cos37 and sin37 respectively?
4/5,3/5
Four fifths, three fifths
Calculation: 1. Sin ^ 2 (48 °) + sin ^ 2 (42 °) - Tan 44 ° Tan 45 ° Tan 46 ° 2. Tan 53 ° cos 37 ° and COS 53 ° sin 37 ° 2
Sin ^ 2 (48) + sin ^ 2 (42) - tan44 * tan45 * tan46 = sin ^ 2 (48) + cos ^ 2 (90-42) - tan44 * 1 * cot (90-46) = sin ^ 2 (48) + cos ^ 2 (48) - tan44 * cot44 = 1-1 = 0sin53 * cos37 + cos53 * sin37 = sin (53 + 37) = sin90 = 1

Junior high school algebra to prove the problem, the use of the ratio of proportion in the theorem Ask the teachers and students of junior high school for a proof of junior high school algebra, It is known that a = B + C + 1; d = e + F + 1; g = H + I + 1; Proof: (D-A) / (D-G) = (E-B) / (E-H) = (F-C) / (f-I) Should be the use of proportion in the split ratio theorem After so many years of reading, I finally forgot all my junior high school mathematics, The recommended answers are: Let Ka = IB + JC + 1 a=b+c+1->k1A=i1B+j1C+1 d=e+f+1->k2A=i2B+j2C+1 G = H + I + 1 - > K3A = i3b + j3c + 1 Substituting (D-A) / (D-G) = (k2-k1) a / (k2-k3) a = (k2-k1) / (k2-k3) Similarly, (E-B) / (E-H) = (F-C) / (f-I) = (k2-k1) / (k2-k3) It has been proved But there are some questions: (E-B) / (E-H) should not be equal to (i2-i1) / (i2-i3), how can it be equal to (k2-k1) / (k2-k3)?
