Prove that (sinA+cosecA)²+(cosA+secA)²=7+tan²A+cot²A

{(sin A + cos e c A)}^{2} + {(cos A + sec A)}^{2} = 7 + {tan}^{2} A + {cot}^{2} A

{(sin A + cos e c A)}^{2} + {(cos A + sec A)}^{2} = {tan}^{2} A + {cot}^{2} A + 7

(s i n A + c o s e c A)^{2} + (c o s A + s e c A)^{2} = 7 + t a n^{2} A + c o t^{2} A .
