Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class 9, Class 10, Class 11 and Class 12 Sep 30, 2024 ... Thus, the value of 4sinA−cosA4sinA+cosA​ is 911​. sinA. cosA. = -2cos2A. 2. a. On the ABC triangle it is known that cosA.cosB = sinA.sinB and. cosA.cosB = sinA.sinB Define the shape of the ABC triangle and the ... How can I solve sinA-cosA=1 where 0 degree<=A<=90 degree. Thank you. Nazrul,. One way to approach this problem is to use sin2A = 1 - cos2A and hence write. Given sinA = cosA We know that sin 45 = cos45 = 1/ root2 Hence, A = 45 degrees Therefore, 2tan 2 A + sin 2 A - 1 = 2tan 2 45 o + sin 2 45 ... SinA'-AW*SinE'*CosA'. Delta El = IE - TF*CosE' +AN*CosA' + AW*SinA'. where A' and E' are the raw telescope azimuth and elevation, IA and IE the azimuth and ... Sep 10, 2016 ... (secA-cosecA)(sec^2+cosec^2A+secAcosecA)={(1+cosA/sinA+sinA/cosA) (sinA-cosA)}/(1/cosA -1/sinA)(1/cos^2A = sinB cosC + sinC cosB + sinC cosA + sinAcosC. + sinAcosB + sinB cosA. = sinA(cosB + cosC) + sinB(cosC + cosA). + sinC(cosA + cosB). (9). Since 0 < sinA ≤ 1 ...
