Webb29 sep. 2012 · If cos9A = sinA and 9A 90*, then the value of tan 5A is. Asked by 29 Sep, 2012, 10:14: PM Expert Answer 9A < 90* means A < 10*. A < 10* means A < 90*. For X between 0* to 90*, the values of sin X are different. So, A = 9A. That is 8A = 0. So, A = 0*. Now, 5A = 5 × 0* = 0*. Hence, tan 5A = tan 0* = 0. Webb∴ The value of \(\rm \frac{{\cos A - \cos 5A - \cos 9A + \cos 13A}}{{\sin A - \sin 5A + \sin 9A - \sin 13A}}\) is tan 4A. Download Solution PDF. Share on Whatsapp Latest SUPER …
