If secQ +tanQ =p , then find the value of cosecQ |
| Answer» Sec + tan= p -(1)Sec^2 - tan^2 = 1So. (Sec+ tan)( sec- tan) = 1 Put sec+tan= P. ,so u will getSec - tan =1/p-(2) Adding eq. 1 and 2 u get Sec + tan + sec - tan= p + 1/p2sec = p^ 2 + 1/ p- (3)Subtracting eq. 1 and 2 U get 2 tan = p^ 2 - 1 / p-(4) Take ratio of eq 3 and eq 4So sec/ tan = p^2 +1 / p^2-1 = cosecA = p^2+1 / p^2-1 Hope u understand otherwise contact me 6265790757 | |
