Prove that sin square theta ➕ cos square theta =1 |
|
Answer» U know the ratio of sin theta and cos theta , sin theta =p/h and cos theta =b/h .put in L.H.S ,p²/h²+b²/h²=1..................only put the ratio of sin theta and cos theta and solve it , you\'ll find value 1 and it proved ...i hope it help u ? P2+b2/h2 = h2 / h2 = 1 RHS LHS SIN 2 + cos 2 =( p/h)2 + (b/h)2 Its easy but how i send pic of ans Plz ans. |
