Can you help me to my problem the formula in the photo thank you. Question:Find the value of cos (A+B) for A terminating in quadrant III and B terminating in quadrant IV where sin A= -1/3 and cos B= 2/5. STANDARD SIGNS OF THE TRIGONOMETRIC FUNCTIONS IN THE FOUR QUADRANTSAll six trigonometric functions are positive in quadrant I. Only sine and its reciprocal are positivein quadrant II. Only tangent and its reciprocal are positive in quadrant III. And only cosine and itsreciprocal are positive in quadrant IV.Quadrant IQuadrant IIQuadrant IIIQuadrant IV Other Trigonometric FunctionsSin (A + B) = Sin A cos B + Sin B cos ASin (A- B) = Sin A Cos B - sinB cos Aios (A + B) = cos A Cos B - sin A Sin BCas (A-B) = cos A Cos B + sin A sin BSin 20 = 2 sin & Cas &Cos 24 = Ces* - Sin+Tan A + Tan BTun (A+ B) =|- Tan A Tan B2 TantTan 2+ =|- Tan' 4
