حل سؤال لإيجاد اتجاه محصلة عدة إزاحات نستخدم القانون tanθ تساوي؟
الإجابة هي:-
Ry/Rx.
عند حل سؤال لإيجاد اتجاه محصلة لعدة إزاحات، يمكننا استخدام قانون الجيب التمامي المعروف بأن تان زاوية θ تساوي النسبة بين الإزاحة الرأسية (Ry) والإزاحة الأفقية (Rx). بمعنى آخر، نقسم الإزاحة الرأسية على الإزاحة الأفقية لنحصل على قيمة تانجينت زاوية θ. استخدام هذا القانون سيساعدنا في تحديد اتجاه المحصلة باستخدام القيم المعطاة للإزاحات الرأسية والأفقية.
